Product Description
Product Overview
The Caddock Type SR Precision Current Sense Resistors are designed for efficient current monitoring and control applications. Utilizing Caddock's Micronox resistance films, these resistors offer non-inductive performance in a compact footprint that minimizes circuit board space. They feature Kelvin terminals for four-wire resistance measurements, ensuring accuracy. Available in a wide range of standard resistances from 0.005 to 1.00, custom values can also be manufactured for high-quantity applications. These resistors are ideal for applications requiring precise current sensing and control.
