TGH600 Series Datasheet

600 Watt Thick Film SOT227 Package

Due to the TGH600's non-inductive design, they are deally suited for high-frequency and pulseload applications. The TGH600 series resistors are designed for direct mounting onto a heatsink and provides up to 600 watts of power dissipation. Popular applications include variable speed drives, power supplies, control devices, telecom, robotics, motor controls, and other switching designs.

Derating

Derating (thermal resistance): 8.33 W/K (0.12 K/W) (for conf. 1, 2, 3) Best results can be obtained by using a thermal transfer compound with a heat con- ductivity of at least 2.9 W/mK. The flatness of the cooling plate must be better than 0.05 mm overall. Surface roughness should not exceed 6.4 μm.

THIS PRODUCT IS DESIGNED FOR USE WITH PROPER HEATSINKING.

Maximum base plate temperature of the resistor must be monitored and kept within specified limits to establish the power rating. Best technique is to attach a thermocouple to the side of the base plate of the resistor. Temperature of plastic housing or heat sink cannot be used to establish rating of the resistor.
