Product Overview
The Caddock MP900 and MP9000 Series Kool-Pak Power Film Resistors are designed for high-power applications, featuring a unique construction with Micronox resistance film fired onto a flat ceramic substrate. These resistors offer non-inductive performance and an exposed ceramic heat-dissipating mounting surface, allowing for efficient thermal management similar to power semiconductors. Available in TO-126, TO-220, and TO-247 style packages, they provide robust power handling capabilities with resistance values ranging from 0.010 ohm to 1 K. Ideal for applications requiring reliable power dissipation and thermal stability.
