Product Overview

The Caddock Type MS Power Film Resistors are axial-lead resistors designed for high-performance applications, offering a wide resistance range and a maximum operating temperature of +275C. These resistors deliver full power and voltage ratings without derating, providing non-inductive performance and extending the critical resistance value. They are constructed with Caddock's proprietary Micronox resistance films, fired onto a ceramic core at high temperatures for outstanding stability under demanding conditions. The patented serpentine pattern ensures efficient non-inductive construction, leading to faster settling times and minimal distortion in high-frequency circuits. Manufactured under intensive controls and rigorous quality assurance, Type MS resistors are suitable for applications requiring high reliability and precise performance.
