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 exceptional stability, even at elevated temperatures up to +275C. Featuring Caddock's patented non-inductive serpentine resistive pattern, these resistors minimize inductive effects, leading to faster settling times and reduced distortion in high-frequency circuits. Constructed with Micronox resistance films fired onto a ceramic core, they provide superior long-term stability and reliability, making them ideal for simplifying circuit design and reducing equipment cost and complexity.
