50 W Power Resistor, Thick Film Technology, TO-220 FEATURES • 50 W at 25 °C heatsink mounted CAPACITANCE RESISTOR TO GND 5.7 - 6 pF
• Adjusted by sand trimming • Leaded or surface mount versions • High power to size ratio • Non inductive element • Material categorization: For definitions of compliance please see www.vishay.com/doc?99912
Because of the knowledge and experience in Thick Film technology, Vishay Sfernice has been able to develop a high power resistor in a TO-220 package called RTO 50. The special design of this component allows the dissipation of 50 W when mounted on a heatsink. The ohmic value is adjusted by sand trimming. This process does not generate hot spots as in laser trimming, which could lead to microcracks on each side of the curve. This process improves the reliability and the stability of the resistor and at the same time gives a good overload capability.

CHOICE OF THE HEATSINK The user must choose according to the working conditions of the component (power, room temperature). Maximum working temperature must not exceed 155 °C. The dissipated power is simply calculated by the following ratio: 1 T P = ------------------------------------------------------------------------------------------R TH (j - c) + R TH (c - h) + R TH (h - a)
P: T: RTH (j - c): RTH (c - h):
RTH (h - a):
Expressed in W Difference between maximum working temperature and room temperature Thermal resistance value measured between resistive layer and outer side of the resistor. It is the thermal resistance of the component: (Special Features Table) Thermal resistance value measured between outer side of the resistor and upper side of the heatsink. This is the thermal resistance of the interface (grease, thermal pad), and the quality of the fastening device Thermal resistance of the heatsink
Example: RTH (c - a): For RTO 50 power rating 13 W at ambient temperature + 30 °C Thermal resistance RTH (j - c): 2.6 °C/W Considering equation (1) we have: T 155 °C - 30 °C = 125 °C T -------- = 9.6 °C/W RTH (j - c) + RTH (c - h) + RTH (h - a) = ------- = 125 P

OVERLOADS
POWER RATING
The applied voltage must always be lower than the maximum overload voltage of 750 V. The values indicated on the graph below are applicable to resistors in air or mounted onto a heatsink.
The temperature of the heatsink should be maintained within the limits specified. To improve the thermal conductivity, surfaces in contact should be coated with a silicone grease and the torque applied on the screw for tightening should be around 1 Nm.
