Fast-Acting Chip Fuses
Fast-Acting Chip Fuses
Fast-acting chip 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 diffusionrelated aging, improves product reliability and resilience,
and enhances high-temperature performance in a wide
range of circuit designs.
These RoHS-compliant surface mount devices offer
strong arc suppression characteristics and facilitate the
development of more reliable, high performance
consumer electronics such as laptops, multimedia
devices, cell phones, and other portable electronics.
