PCB Mount Circuit Protection Compact Design Long Leaded PVC Cap Fast Acting Micro Miniature Fuse F 5A 250V
What is a Micro Fuse?
A micro fuse is a radial leaded subminiature fuse, offered in either a cylindrical or rectangular form factor. Micro fuses were originally designed for the U.S. Space Program. The micro fuse is made with either glass, plastic or metal bodies. They are designed to be electrically equivalent to miniature glass cartridge, fuses in a smaller package with higher tolerance to impact and vibration. Micro fuses can plug, in to a PC board mounted fuse holder. Micro fuse voltage, ratings typically range from 65 volts AC to 300 volts AC. Micro fuses with voltage ratings up to 450 volts DC are also available. Micro fuses are offered in fast acting, or time lag, versions. Micro fuses are typically built in accordance with UL 248-14, and CSA C22.2/No.248.14 or IEC 60127-3, standards. Some fuse micro series are also offered in MIL Spec, versions.
