The JFC0603-0500FS is a surface mount fuse manufactured by JDT. It is a RoHS compliant 0603 sized fuse, which means it is a fuse designed to occupy the smallest PCB space possible. The fuse is rated at 5A (5000mA) and has a voltage rating of 32V. It is made of nickel-chromium-copper alloy and is designed to be used on electronic circuits.The fuse is designed with overcurrent protection and current limiting in mind as it automatically trips and delivers protection to the circuit when the current exceeds its rated value. It can be used in applications such as automotive, industrial, computer, telecommunications and consumer electronics.
