Radial microfuses are non-regenerative fuses used for through-hole type substrates, and do not expose conductive parts when mounted on printed circuit boards, simplifying insulation design and contributing to higher mounting density.

Radial type Micro fuses are those of the non-reusable type mounted on PCBs of the through-hole type, with their conducting parts shielded when fuses are mounted on PCBs, facilitating electric insulation design and high-density mounting.
