Product Overview

The Caddock Type MS Power Film Resistors are high-performance axial-lead resistors designed for demanding applications. They offer a wide resistance range, high power and voltage ratings, and excellent long-term stability, simplifying circuit design and reducing costs. These resistors are ideal for high-frequency circuits due to their non-inductive construction, which minimizes flux fields and ensures faster settling times. Manufactured under intensive controls using Caddock's proprietary Micronox resistance films, they provide outstanding stability under high ambient temperatures, thermal shock, and high power densities.
