Fast Acting Over-molded Fuse

The SKY87604 is a fast acting fuse with high I2t values, which enables high inrush current withstanding capability.

The SKY87604 is an over-molded fuse providing sufficient clearance from external metallic material. By design, the SKY87604 prevents contact between metallic material and the body of the fuse, so the minimum clearance regulated by UL can be easily met. A UL recognized component fuse must be used with this product. Refer to Table 5 for more information.

The SKY87604 is available in a space-saving 3.0 mm x 3.0 mm, 4-lead MCM, Pb-free package.
