Raychem Fast Acting Fuses

Fast-acting Surface-mount Fuse

Fast-acting fuses help provide overcurrent protection on systems using DC power sources up to 63VDC. The fuse's monolithic, multilayer design provides the highest hold current in the smallest footprint, reduces diffusion-related aging, improves product reliability and resilience, and enhances high temperature performance in a wide range of circuit protection designs. This helps facilitate the development of more reliable, high-performance consumer electronics such as laptops, multimedia devices, cell phones, and other portable electronics.
