Abstract

A microfuse (10) with a ceramic chip (12), thick film pads (14), fusible wire (16), attached to pads (14) without solder or flux, in an insulating enclosure or fuse tube (40). Ferrules (42) are attached to metallized areas (14) with solder (44). Performance and manufacturing of fuse (10) is improved by utilizing a wire bonding technique to improve the quality of the manufacturing process and increase the reliability of the fuse, and to reduce manufacturing cost.
