Product Description
Product Overview
Type SR Precision Current Sense Resistors from Caddock Electronics, Inc. are designed for efficient current monitoring and control applications. These non-inductive resistors utilize Caddock's Micronox resistance films to achieve a compact footprint, minimizing circuit board space. Featuring Kelvin terminals for accurate four-wire resistance measurements, they are available in standard resistance values from 0.005 to 1.00, with custom values available for high-quantity applications. The resistors offer a wide operating temperature range of -40C to +150C and are encapsulated in polymer over the resistance element.
