Vishay LPS1100 power thick film resistor

Vishay has released a power thick film resistor, claimed to be first in the compact 57 x 60 mm package to offer a power rating of 1100 W at a heat sink temperature of +25°C.

The LPS1100 has high-temperature derating and a broad range of resistance values.

It is non-inductive (<0.1 μH) and provides a resistance range from 1 Ω to 1.3 kΩ. Designed for easy mounting to a heat sink, the device has a compact footprint and low 25 mm profile.

With its high power capabilities and high dielectric strength to 12 kVRMS, the resistor is intended for power supply, inverter, converter, HEV-EV battery management, and snubber, chopper, precharge, discharge, filtering and crowbar resistor applications. Typical end products will include windmill turbines, X-ray and oncology tables, trains and large UPS drives.
