The MP930-47.0-1% Kool-Pak® power film resistor from Caddock has a heat sink mountable design featuring an exposed ceramic heat dissipating mounting surface and is available at a low cost. It has a resistance of 47.0Ω with a power rating of up to 30W at +25°C (case temperature derated to zero at +150°C). The MP930-47.0-1% is a stocked item here at Rhopoint with a tolerance of ±1.0%, with ±5.0% and ±20.0% options available upon request. 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.
