TGH Series C) 120 and 200 Watt SOT227Package Thick Film Power Due to their non-inductive design, these resistors are ideally suited for high-frequency and pulse-load applications. Available in 120- or 200-watt sizes, this resistor is designed for direct mounting onto a heatsink. Popular applications include variable speed drives, power supplies, control devices, telecom, robotics, motor controls, and other switching designs. Heat Sink Nickel-plated copper Contacts Nickel-plated copper Substrate Al203 (96%) Molding Compound High-performance epoxy, compliant to UL94-V0 Terminal Nuts American standard 303 stainless steel Resistance Range 0.1Q to 1MQ Tolerance ±5%; other tolerances available on request Temperature coefficient: ±250ppm (at +105°C ref. to +25°C) Max. Working Voltage 500V (1000V, not to exceed rated wattage using VP*R.) Power Rating at 85°C 120W (see derating) Partial Discharge up to 2,000Vrms/80 pC Voltage Proof Dielectric Strength up to 4,000V DC against ground Heat Resistance to Cooling Plate Rth <0.35 K/W Capacitance/Mass 45pF Working Temp. Range -55°C to +155°C Max. Torque for Base Plate (static) 1.5 Nm Max. Torque for Contacts (static) 1.3 Nm.
