The Littelfuse 04381.75WRA is a 1.75A, 32VAC/32VDC fast-acting surface mount fuse from the 438A series. It is designed for secondary circuit protection in compact automotive electronics, with AECQ compliance ensuring reliability under harsh conditions. The fuse offers a breaking capacity of 50A at rated voltage and a fast blow response time for rapid overcurrent interruption.
Electrical characteristics include a nominal resistance of 1.405 Ω, melting I²t of 0.144 A²s, voltage drop of 0.360 V, and power dissipation of 0.540 W at rated current. The operating temperature range spans -55°C to 150°C, making it suitable for extreme environments.
The fuse is housed in a 0603 (1608 metric) package with dimensions 1.58 mm x 0.85 mm x 0.61 mm, designed for surface mount assembly. It is 100% lead-free, halogen-free, and RoHS/REACH compliant (low confidence for RoHS/REACH, but verified lead-free and halogen-free from datasheet). Agency approvals include CSA and UR.
