Caddock 1Ω Power Film Resistor 50W ±1% MP850-1R-1%

The Caddock MP850 Series Kool-Pak® Power Film Resistors include an integral metal mounting surface for highly efficient thermal transfer. The TO-220 style power package provides 50 W at +25 ºC case temperature, derated to zero at +150 ºC. Composed with Caddock's Micronox® resistance film fired onto a flat ceramic substrate, the substrate is secured to a copper heat sink which becomes the metal mounting surface. The MP850 Series Kool-Pak Power Film Resistors offer a resistance range of 0.20 Ω to 10.0K.

High power film resistors in TO-220 enclosure.
Non inductive.
Electrically insulated enclosure.
These types of components are very useful at high frequencies up to 500 MHz.
