MP8x Series Kool-Pak Power Film Resistors

Caddock MP8x Series Kool-Pak® Power Film Resistors include an integral metal mounting surface for highly efficient thermal transfer. With a TO-220 style power package, the MP8x provides 25W/50W at +25ºC case temperature, derated to zero at +150ºC. Constructed with Caddock's Micronox® resistance film fired onto a flat ceramic substrate, the substrate is bonded to a copper heat sink which becomes the metal mounting surface. The Caddock MP8x Series Kool-Pak Power Film Resistors offer a resistance range of 0.20ohm to 10.0K, non-inductive design.
