Raychem Fast-Acting Chip Fuses

Fast-acting Surface-mount Fuse

Raychem fast-acting chip fuses help protect equipment from damage caused by overcurrent conditions when relative quick clear or open times are required in DC power applications. The fuses' monolithic, multilayer design provides some of the highest current ratings on the market and the smallest footprint. Available in industry standard 0402, 0603 and 1206 chip sizes, they also reduce fuse aging, improve product reliability and resilience, and enhance high-temperature performance in a wide range of circuit protection designs.

As RoHS-compliant and halogen-free, Raychem fast-acting fuses offer strong arc suppression characteristics and facilitate the development of more reliable consumer electronics. Applications include laptops, multimedia devices, cell phones, and other portable electronics.
