Fuse 5mm 250V 500mA

This Sparkfun product is a glass ferrule type fuse, perfectly compatible with 5mm fuse clips. The fuse is rated for 250VAC and can handle a maximum of 500mA. Its working principle is simple and efficient - if more than 500mA passes through the fuse, the small filament inside heats up and breaks, thereby breaking the circuit and potentially saving your circuit from severe damage. This fuse measures 5 x 20mm.

For those working with smaller loads, it may be beneficial to consider a PTC, also known as a resettable fuse. These are capable of handling less current (500mA), but offer the advantage of being set and reset multiple times without causing harm to your system.

The main features of this Sparkfun fuse include a 500mA maximum at 250VAC, a glass cartridge design, and dimensions of 5 x 20mm. It's a reliable and practical choice for protecting your circuits.
