The JK30-090 PTC Fuse DIP RoHS manufactured by Yenji is a regulation-compliant electronic part. The part is designed as a miniaturized PTC fuse that is compliant with the Restriction of Hazardous Substances (RoHS) directive. This directive requires all electrical and electronic products manufactured and sold in the European Union to be free of lead, cadmium, and certain other hazardous substances. It is a dual-in-line package (DIP) which has two parallel rows of pins for mounting onto printed circuit boards. This PTC fuse functions by providing a self-resetting mechanism when an over-current situation is detected, cutting off power and then automatically resetting once the current flow returns to normal. This part is ideal for use in sensitive electronics, providing fast and reliable thermal-based protection.
