120 Watt Power Resistor in the "ISOTOP" Power Device (1x120W / 2x50W / 3x30W acc. Configurations)
| Due to a non inductive design theseelements are ideally suited for highfrequency and pulse load applications. Bydirect mounting on a heatsink significantcost advantages can be realized. Thetype GXP can be supplied in a 2-termi-nal or 4-terminal version. Even tripleresistors are available. Main applicationsare: Variable speed Drives, PowerSupplies, Control Devices, Telecom,Robotics, Motor Controls and otherswitching designs.Specials and custom designedcomponents on request. Derating (thermal resistance):2.86W/°K (0.35°K/W). Best results can be reached by using athermal transfer compound with a heatconductivity of better than 1W/mK | Specifications •Resistance Range: 0.1W to 1MW •Tolerance: ±1%, 2%, 5%,10% •Temperature coefficient:±50, ±100ppm, ±250ppm (at+105°C ref. to +25°C) •Max.
