TE Connectivity FRN Series Fusible Resistor 0.22Ω 5% 0.25W

The TE Connectivity FRN Series Fusible Resistor is a precision-engineered component designed for both resistance and circuit protection. Featuring a flame-proof ceramic resistive element, this resistor acts as a reliable fuse in safety-critical applications. Its unique construction involves a resistive film sputtered onto a ceramic core, with metal end caps force-fitted and tinned copper leads welded for optimal electrical connection. The entire component is then coated with multiple layers of flameproof cement, ensuring high reliability and safety compliance.

This fusible resistor is rigorously tested to guarantee performance, fusing in under 60 seconds when subjected to 16 times its rated power. This makes it an ideal choice for protecting sensitive electronic circuits from overcurrent conditions, preventing damage to more expensive components. The technology behind the FRN series also allows for the manufacture of custom fusible characteristics to meet specific application requirements.
