What does a ceramic fuse look like.

A ceramic fuse is built to withstand high temperatures. The film is formed when a short circuit melts the fuse element causing a deposit to be seen on the inside of the fuse barrel as a film. They are very small and look like a tiny silver candy bar. Medium voltage fuses may have liquid filled envelopes to assist in the extinguishing of the arc.

Testing a ceramic fuse is the only way to tell if the fuse has blown. A ceramic fuse however shows no damage upon visual inspection. These fuses are designed to protect individual components of a system instead of one fuse protecting the entire item. You can test your smd fuses for proper working order with a basic multi meter and a steady hand.

The more thermally stable fuse is typically filled with sand in order to prevent the conductive film from forming. Smd fuses are used in fine electronic equipment and video game systems. Blade fuses are sometimes physically difficult to pull out but most vehicles come with a fuse puller tool that is located inside one of the fuse boxes or attached to a fuse box lid. Although it is fairly easy for a practiced eye to identify car fuses on sight you can also look at a visual guide to help determine which type of fuse you need to.

Filling a fuse body with sand provides additional cooling of the arc and increases the breaking capacity of the fuse.
