The 0437003.WR is a 3A, 32V fast-acting surface mount fuse from Littelfuse, part of the 437 series. It is designed for overcurrent protection in circuits requiring fast response and high temperature stability up to 150°C. The fuse is 100% lead-free, halogen-free, and RoHS compliant, with a ceramic construction that provides excellent inrush current withstand capability.
Key electrical specifications include a nominal current rating of 3A, voltage rating of 32V AC/DC, and a breaking capacity of 50A at 32V AC / 35V DC. The fast blow response time ensures rapid protection for sensitive components. The melting I²t is 0.4 A²s, supporting high inrush currents.
The fuse is housed in a 1206 (3216 metric) surface mount package with dimensions 3.20mm x 1.63mm x 0.82mm. It is suitable for leaded and lead-free reflow/wave soldering. Operating temperature range is -55°C to +150°C. The device is approved by CSA and UR, and conforms to EN60127-1 and EN60127-7 standards.
