Design Information Molybdenum Permalloy, Hi-Flux and Super-MSS Powder cores are wound with magnet wire to make transformers or inductors. Maximum allowable energy dissipation for a given value of energy storage (inductance and current) or transformation (voltage and current), guide the selection of core material and size. Energy dissipation is usually specified in terms of maximum temperature rise, minimum efficiency or minimum Q value. (Q is 2π times the ratio of peak energy stored to energy dissipated during one period of current flow.) Consider the following when choosing a core material: 1. Molybdenum Permalloy Powder (MPP) cores provide the maximum Q and lowest core loss. MPP is the most stable core with respect to temperature and AC Flux. It has the widest range of permeabilities and is considered the premium material for direct current output inductors of Switched Mode Power Supplies. It is useful into the Megahertz range of frequencies. MPP cores are an excellent choice for precision audio frequency tuned circuits, High Q Filters, Loading Coils, RFI Filters and many other precision inductor applications. 2. Hi-Flux cores are a 50% Nickel 50% Iron distributed gapped powder core. HF has up to 15,000 Gauss saturation flux density and core losses significantly lower than iron powder cores. These cores are ideal for Switching Regulator Inductors, In Line Noise Filters, Pulse and Fly-Back Transformer applications. When used in applications with high dc current, HF cores can provide a reduction in inductor size as well as total cost. 3. Super-MSS is an improved Sendust material, originally developed by Arnold Engineering. It is designed to replace iron powder by offering much lower losses, with energy storage capability higher than MPP. Super-MSS cores are an excellent choice for energy storage and filter inductor applications in Switch Mode Power Supplies. The low loss properties of SuperMSS cores minimizes the temperature rise at power frequencies to well below that of a similar sized iron powder core. The DC Bias characteristics of Super-MSS are also excellent compared to iron powder of similar permeabilities and size. For reference, some basic electromagnetic terms and relationships used to design with magnetic powder cores are defined, followed by graphs showing typical values for material characteristics essential to transformer and inductor design. The final section of this catalogue contains data for specific core sizes and Q curves for Molybdenum Permalloy Powder (MPP) cores.

Units of Measure For historical reasons, the Centimeter-Gram-Second (CGS) system is used in this catalog. Conversion between the System International (SI) and CGS System is simplified using the following table.

Design Information (Cont.) The “Normal Permeability versus Flux Density” graph shows normal permeability as a function of peak flux density, B. le

Most design procedures involve choosing a peak operating magnetic flux density to help determine the core size. Peak operating flux density is limited by the core material saturation flux density or by the core material loss. After choosing the material and operating flux density and determining the core size, Faraday’s Law (discussed below) is then used to calculate the number of turns, N. Finally, a permeability is selected to provide the required inductance.

Figure 1. Effective Core Parameters

Ae

For toroidal powder cores, the effective area is the same as the cross sectional area. By definition and Ampere’s Law, the effective magnetic path length is the ratio of winding ampere-turns (NI) to the average magnetizing force across the core area from inside diameter to outside diameter. Using Ampere’s Law and averaging the magnetizing force gives the formula for effective path length. le =

A wide range of permeabilities are offered to satisfy various inductance requirements.

O.D. = outside diameter of core. I.D. = inside diameter of core.

Ampere’s Law (also discussed below) gives the peak value of magnetizing force, H, based on the number of turns, peak magnetizing current (the total current of an inductor and “no-load” current in a transformer primary) and core magnetic path length. As can be seen in Figure 2, selecting the permeability sets the peak magnetic flux density so it matches the value chosen at the beginning of the design procedure. Also, for Molybdenum Permalloy Powder (MPP), the following selection chart gives the permeability that yields maximum inductance for a given magnetizing force.

Inductance factors are measured using a single layer winding with closely spaced turns. Flux densities and test frequencies are kept as low as practical, usually less than 40 gausses and 10 kHz or below. The “Normal Permeability versus Flux Density” and “Typical Permeability versus Frequency” graphs can be used as guides to define low-level test conditions for the various permeabilities and materials.

INCRMENTAL PERMEABILITY

The inductance factors listed for each core size are based on incremental relative permeabilities. With no direct current bias and at low flux densities, the normal and incremental permeabilities are the same. The incremental permeability decreases with direct current bias as indicated by Figure 2 and shown in the “Incremental Permeability versus DC Bias” graphs.

Design Information (Cont.) The “Normal Magnetization Curves” can be used with the “Typical Incremental Permeability versus DC Bias Curves” to estimate the direct current magnetic flux density for a chosen percentage of incremental permeability. For example, 125µ Molybdenum Permalloy Powder has 50% incremental permeability at just under 50 oersteds. The corresponding flux density is about 4500 gausses (0.45 tesla) according to the normal magnetization curve. Surveying the other permeabilities suggests that this could be used as an approximation of the DC flux density where Molybdenum Permalloy Powder has 50% of its original incremental permeability.

The magnetizing force determines the estimate of magnetic flux density using the normal magnetization curves. See the above section on permeability. The relative permeability is, by definition:

µ = The effective area is considered the total area of the core cross section as shown in Figure 1. The area occupied by magnetic alloy is less than this area and decreases with decreasing permeability. Catalog data for the different permeabilities include effects from the smaller magnetic alloy areas. Also, Bmax is an average maximum flux density value over the core cross section. The flux density is greater toward the inside diameter and smaller toward the outside diameter as shown by Ampere’s Law and described in the following.

Winding Notes The d.c. winding resistance for an average winding can be calculated by:

Molypermalloy Q Curves“.) The graph below is useful for estimating self-resonant frequency. By selecting a winding technique which minimizes the voltage between turns, the distributed capacitance may be reduced. Several winding techniques are available. Dividing the winding into a number of sections, such as 2, 4, or more, or the use of a bankwound coil is effective in reducing the capacitance. In any case, the winding and inter-sector connecting technique should carefully avoid placing the first and last turns adjacent to each other - as they have the highest turn to turn potential, and thus contribute the most to the effective capacitance. Both the moisture content in the dielectric of the winding and the dielectric constant of potting and encapsulating materials increase the effective distributed capacitance.

Rdc = l w Nr 12000

l w = mean length of turn (in.) N = number of turns r = resistance of wire in ohms per 1000 feet (see wire table on page 8.) In addition to the normal d.c. resistance of a winding, there exists an incremental change in the winding resistance due to the skin effects of a.c. current.* This can be approximated by:

Precision wound cores - stable with time and having reproducible temperature characteristics - must have winding strains relieved by temperature cycling. The wound cores must be cycled from room temperature to 125° C., repeating the cycle as many times as necessary to achieve reproducible results. At least one cycle should include a temperature lower than the wound core will be exposed to under operating conditions. This cycling will not only relieve strains, but also remove moisture that is present. Final adjustment of inductance value should be made after the temperature cycling process has been completed.

where x = d

f (1 + .00393 (°C - 20))

d = wire diameter (inches) f = frequency (HZ) °C = operating temperature

The wound cores should be kept dry until they are dipped, potted, or hermetically sealed. Potting and encapsulating compounds should be carefully selected as some may shrink with age or temperature change, and thus affect stability. Cushioning material on the wound cores can minimize this effect.

Minimizing distributed capacitance is an important core winding consideration. A toroidal winding has an effective capacitance which may be considered to be in parallel with the inductance. This is the result of the summation of capacitances from turn to turn, layer to layer, and from parts of the winding to the core. (The effect of this capacitance on the Q and the inductance of the component is discussed in the section ”Notes on

Notes on Molybdenum Permalloy Q Curves Note: The following information applies to frequency tuned circuit applications. The Q formula calculates the ratio of reactance to effective resistance for an inductor and thus indicates its quality. For electrical wave filters, an increase in Q provides sharper cut-off, higher attenuation ratios, and better defined resonance. Q is affected by the distributed capacitance of an inductor's winding. Neglecting the effects of self-resonance caused by the distributed capacitance (see paragraph 4c, below) Q can be calculated, when designing inductors, by this formula: ** Q=

Q = L =  = Rdc = Rac = Rcd =

L Rdc + Rac + Rcd

quality factor inductance (henries) 2 π X frequency (frequency in hertz) dc winding resistance (ohms) resistance due to core losses (ohms) resistance due to dielectric losses in winding (ohms)

The Q curves published in this manual are not to be construed as guaranteed minimum values. Instead they represent what might be attainable under ideal conditions. They were developed theoretically and have been checked with various core sizes and inductances to assure reasonable correspondence to the real world of wire, insulation and winding. The user's ability to get equivalent results depends in part upon his ability to duplicate the assumed conditions. These are: 1. A "full-wound core" is defined to be one in which the minimum winding ID or residual hole left after winding is one-half of the inside diameter of the core.

b. The second factor is caused by dielectric loss. Dielectric loss resistance is significant at higher frequencies and can be calculated from the equation found in Terman’s Handbook.*** Rcd = d3 L2 Cd d =power factor of distributed capacitance Values of d 125µ & over .0118 60µ .0417 26µ .0750 14µ .0900  = 2π X frequency in hertz L = Inductance in henries Cd = distributed capacitance in farads c. The most dramatic factor is the effect of self resonance of the distributed capacitance and the inductance. For small inductances, such as the 0.001 henry or the 0.01 henry curve for each core, the self-resonant frequency f° is well above the normal useful frequency range of the component. Therefore, these curves tend to indicate the component performance with a negligible effect of self resonance. The distributed capacitance and the self inductance determine a self-resonant frequency according to: f° =

It should be noted that when f is 20% of f°, Qf is 96% of its original value. However, when f is 70% of f°, Qf drops to 51% of its original value. The apparent value of the inductance, La, is also affected as follows: L

La =

4. Three factors affect the high frequency performance of an inductor. a. The most fundamental is the loss of the core material which is mostly responsible for the negative slope of the low inductance curves at frequencies above the frequency of maximum Q. This is calculated from Legg's equation (see next section).

hertz.

2 π LC d

At some lower frequency, f, the value Qf can be calculated from:

2. This leaves a useful winding area which is three-quarters of the available window area. It was assumed that 70% of this space would be filled with copper wire including heavy synthetic film insulation. 3. The dc resistance of a full-wound core varies as the square of the number of turns in the same manner that the resultant inductance varies as the square of the turns. Therefore, each core size has a table of calculated ohms per millihenry based on the "full-wound core" definition above. This resistance determines the positive slope of the low frequency portion of the Q curve and is assumed to be independent of inductance.

5. Because the distributed capacitance is determined by the winding method, the user can obtain different results from those plotted, depending on this value of the capacitance. Each Q curve is marked with the capacitance value used. ***Radio

Notes on Molybdenum Permalloy Q Curves (Cont.) Molybdenum Permalloy Core Loss at Low Magnetic Flux Densities LEGG'S EQUATION1...total core loss at low flux densities is the sum of three component losses - hysteresis, residual and eddy current. Values of typical loss coefficients are found in the following table for each permeability. The core loss in terms of ohms per henry per unit of permeability is calcuated from Legg's Equation: Rac = µL
