The Littelfuse 0438003.WR is a 3A fast-acting surface mount fuse from the 438 Series, designed for overcurrent protection in high ambient temperature environments up to 150°C. It is rated for 32VDC and 12VAC with a breaking capacity of 50A at rated voltage. The fuse features a nominal resistance of 0.0255 ohms, melting I²t of 0.2922 A²sec, and a voltage drop of 0.093V at rated current.
This 0603 (1608 metric) package fuse is 100% lead-free, RoHS compliant, and halogen-free, making it suitable for leaded and lead-free soldering processes. It holds agency approvals from CSA, UL, CE, and UKCA, ensuring compliance with international standards.
With a fast-acting response time and high I²t values typical of Littelfuse ceramic fuses, it provides excellent inrush current withstand capability. The surface mount design allows for automated assembly in compact circuit boards, ideal for space-constrained applications.
