DESCRIPTION

The TR/MCR-1 is a subminiature through-hole electronic fuse from the MCR Series featuring fast-acting, solid matrix construction with a 1 ampere rating. It is rated for 125V AC and 125V DC with an interrupting rating of 50A AC and 300A DC, and exhibits a typical voltage drop of 0.24 volts at 100% rated current. The fuse features an axial-leaded design with tin-lead plated copper lead wires (0.025" diameter), a high-temperature thermoplastic body (UL 94 VO), and operates reliably over a temperature range of -55°C to 125°C. It meets UL and CSA certification standards and is designed to carry its rated current for a minimum of four hours, with fast response at 250% of rated current (5 seconds maximum). This fuse is ideal for circuit protection in electronic equipment, instrumentation, and consumer devices where reliable overcurrent protection and compact form factor are essential.
