LPSxxx Thick Film Power Resistors


Vishay's non-inductive devices offer resistance range from 0.3Ω to 900kΩ and dielectric strength up to 12kVRMS


Vishay/Sfernice - LPSxxx Thick Film Power ResistorsVishay/Sfernice's LPS300, LPS600, and LPS800 series thick film resistors are non-inductive (< 0.1 µH) and provide a wide resistance range of 0.3Ω to 900kΩ. Featuring compact footprints of 57mm by 60mm and low weight of 83g, these devices save valuable space on the circuit board, allowing designers to reduce the size of their end products.

With their high power capabilities and high dielectric strength of 12 kVRMS, LPSxxx resistors are intended for power supply, inverter, converter, snubber, and discharge resistor applications in windmills, trains, scanners 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 10Ω and tolerances from ±1% to ±10%. The RoHS-compliant resistors offer high-temperature performance from -55°C to 120°C (LPS300), 155°C (LPS600), and 175°C (LPS800).
