TGH600 Series 600 Watt Thick Film SOT227 Package Due to the TGH600 s non-inductive design, they are deally suited for high-frequency and pulse- load 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. cHaracTeriSTicS Ohmic range 0.25 to 1K Derating Resistance tolerance 10% 5% on request 100 600 Temperature coefficient 250ppm/C (others on request) 80 480 Maximum working voltage 1000V DC (higher voltage on request) Power rating 600W at 85C bottom case temperature.

Maximum base plate temperature of the resistor must be monitored and kept within specified limits to es- tablish the power rating. Best technique is to attach a thermocouple to the side of the base plate of the resis- tor. Temperature of plastic housing or heat sink cannot be used to establish rating of the resistor. rev 9/18-1 1-866-9-OHMITE Intl 1-847-258-0300 Fax 1-847-574-7522 www.ohmite.com info ohmite.com 157
