500mA 125V Fast Blow Axial Fuse

Compact 500mA Fuse for Circuit Boards

This 500mA fuse provides compact overcurrent protection for printed circuit boards, consumer electronics, power supplies, instrumentation, and repair projects. Its small axial package measures only 0.110 inch in diameter x 0.280 inch in length (2.80 mm x 7.11 mm), making it useful when circuit board space is limited.

Axial leads allow the fuse to be installed directly into standard through-hole PCB locations. This board-mount design is a convenient choice for DIY electronics, equipment repairs, prototypes, and replacement applications that require a tiny fuse instead of a traditional cartridge-style fuse.

500mA Fast Blow Fuse Protection

The 500mA fast blow fuse has a fast-acting response that helps interrupt excessive current before it can cause further circuit damage. It is rated for 125 V AC and 125 V DC, with an interrupting capacity of 50 A AC and 300 A DC.

With a current rating of 500 mA (0.5 A), this fuse is suitable for low-current electronic circuits that require dependable, quick-response protection.

Axial Lead Through-Hole Fuse

This axial lead fuse is part of the PICO II 251 series and is designed for through-hole soldering. Its compact body and extended operating temperature range make it suitable for consumer electronics, test equipment, power supply circuits, instrumentation, and other space-conscious PCB applications.

The fuse is supplied in bulk packaging and sold individually, so you can order the exact quantity needed for a repair or project. The manufacturer part number is 0251-500MXL, and the part status is active.
