The MP915 Kool-Pak® power film resistors from Caddock are a low cost, heat sink mountable design featuring an exposed ceramic heat dissipating mounting surface. The resistance range is from 0.02Ω up to 1KΩ with a power rating of up to 15W at +25°C case temperature derated to zero at +150°C. The MP915 series tolerance options available are ±1.0% ( standard), ±5.0% and ±20.0% depending on the resistance values required. The MP915 series Kool-Pak® power film resistors are constructed with Caddock’s Micronox® resistance film fired onto a flat ceramic substrate. The terminal attachment and resistance element geometry are configured to provide outstanding non-inductive performance.
