electronicsThe ECC58066EU with Fuse Holders 5mm*20mm RoHS manufactured by Xucheng Electronics is an electronic part made up of five components, each performing a specific purpose, to protect electrical circuits from damage caused by high currents. Included in the component is a ceramic tube with a metal casing, five metal contacts, a fuse holder, and a RoHS compliant rating. The ceramic tube allows the fuse holder to be isolated from the rest of the circuit, keeping it from short circuiting. The contacts of the fuse holder hold the fuse in place, while the metal casing keeps the contacts from coming into contact with any other part. The RoHS compliant rating shows that the product has been tested for hazardous materials and meets specific environmental regulations.
