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.
