Caddock MP930 Series

Caddock MP930 Series

The MP930 Kool-Pak® power film resistors from Caddock have a heat sink mountable design featuring an exposed ceramic heat dissipating mounting surface and is available at a low cost. The resistance range is from 0.02Ω up to 4.99kΩ with a power rating of up to 30W at +25°C (case temperature derated to zero at +150°C). The MP930 series tolerance options available are ±5.0% from 0.02Ω up to 0.04Ω, ±1.0% from 0.05Ω and above with ±5.0% and ±20.0% options available for most resistance values. The MP930 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.
