thick film power resistorsVishay Intertechnology, Inc. released 300-W, 600-W, and 800-W thick film power resistors featuring a small size and a broad range of resistance values. The LPS300, LPS600, and LPS800 devices are non-inductive (<0.1 µH) and provide a resistance range of 0.3 Ohms to 900 kOhms. Featuring compact footprints of 57 mm x 60 mm, low weight of 83 g., high-power capabilities and high dielectric strength of 12 kVRMS, the devices are intended for power supply, inverter, converter, snubber, and discharge resistor applications in windmills, trains, scanner and X-ray tables, and large UPS drives. Thermal resistance for the LPSxxx resistors at rated power and + 85°C is 0.112°C/W junction-to-case. The devices feature a standard temperature coefficient of ±150 ppm/°C for values above 10 Ohms and tolerances from ±1 percent to ±10 percent. Pricing in standard 100-piece orders is $25 for the LPS300, $30 for the LPS600, and $50 for the LPS800.
