The TR1/MCRW3A is a fast-acting subminiature Microtron fuse designed for circuit protection in electronic applications. It features a 3A current rating with a voltage rating of 125V AC / 300V DC, a typical resistance of 0.031O, and a typical melt current of 0.9A. The fuse employs axial-leaded wire-in-air construction with matte tin-plated copper leads, a molded plastic body (UL 94V0), and a ceramic tube element, ensuring reliable performance across an operating temperature range of -55°C to 125°C. With fast-acting characteristics (5 seconds maximum opening time at 200% of rated current), low resistance values, and compliance with UL and CSA standards, this fuse is ideal for protecting sensitive electronic circuits in industrial, consumer, and telecommunications equipment where rapid fault response is critical.
