The Littelfuse 0440001.WR is a board mount fuse (cartridge style excluded) designed for overcurrent protection in compact electronic circuits. It is rated for 1A continuous current and 50V AC/DC voltage, with a fast blow response time to quickly interrupt fault currents. The fuse has a breaking capacity of 50A at rated voltage and a melting I²t of 0.21054. It operates over a wide temperature range of -55°C to 150°C.
The fuse is housed in a 1206 (3216 Metric) surface mount package with dimensions of 3.20mm x 1.63mm x 0.82mm. It is approved by CSA and UL. The surface mount design enables automated assembly and is suitable for space-constrained applications.
Typical applications include overcurrent protection in power supply lines, battery management circuits, and general-purpose board-level protection in consumer electronics, industrial controls, and telecommunications equipment.
