Jaycar 4A M205 Ceramic Fast Blow Fuse

Higher-current circuit, same problem: you need a fuse that trips before the board takes damage. This Jaycar 4A M205 ceramic fast blow fuse is F-rated — it goes open circuit fast on an overload or short, protecting whatever's downstream. Ceramic construction handles thermal load and arc energy better than a glass fuse at the same 4A spec. Suits a wide range of devices. Add to cart and get back to building
