Vishay / Sfernice

LPSxxx Thick Film Power Resistors

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

LPSxxx Thick Film Power Resistors Vishay/Sfernice's LPS300, LPS600, and LPS800 series thick film resistors are non-inductive (< 0.1 µH) and provide a wide resistance range of 0.3 Ω to 900 kΩ. Featuring compact footprints of 57 mm by 60 mm and low weight of 83 g, 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 10 Ω 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).

Features
  • Wide resistance range: from 0.3 Ω to 900 kΩ
  • High-power dissipation: 300 W, 600 W, and 800 W at 85°C
  • High-dielectric strength: up to 12 kV RMS
  • Small size: 57 mm x 60 mm
  • Non inductive: < 0.1 μH
  • Low weight: 83 g
Applications
  • Wind turbines
  • Inverters
  • Converters
  • Snubbers
  • Discharge resistors
  • Power supplies in trains and medical equipment
