Kool-Pak® Power Film Resistors

The MP9100 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 0.05Ω up to 100Ω with a power rating of up to 100W at +25°C case temperature derated to zero at +175°C. The MP9100 series tolerance is ±1.0% as standard (±5.0% and ±20.0% are available for most resistance values). The MP9100 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.

Use your thermal design experience with power semiconductors in TO-247 style power packages to help you get the most out of this unique family of power resistors. The thermal design issues are the same where power handling capability is based on the case temperature which is maintained in your design.
