Surface Mount Power Film Resistor

The MP725 D-Pak style surface-mount power film resistors from Caddock offer a resistance range from 0.02Ω up to 1KΩ and a power rating of up to 25W at +25°C case temperature. The MP725 series tolerance values available are ±1.0%, ±5.0% and ±20.0% (depending on the resistance value required). These resistors introduce Caddock’s proven Micronox® resistance film system in the widely accepted D-Pak style surface-mount power package. The non-inductive design makes this resistor ideal in high frequency communications, power switching circuits, and snubbers.
