The Littelfuse 045901.5UR is a 1.5A, 125V fast-acting surface mount fuse from the 459 Series, based on Littelfuse PICO fuse technology. It is designed for board-level overcurrent protection in a compact 2-SMD J-Lead package measuring 7.24mm x 4.32mm x 3.05mm. The fuse offers a nominal cold resistance of 0.0816 Ω and a melting I²t of 0.65 A²s, making it suitable for applications requiring precise and rapid response to overcurrent conditions.
This fuse is rated for both AC and DC operation at 125V, with an interrupting rating of 50A AC and 300A DC. It operates over a wide temperature range of -55°C to 125°C and is RoHS compliant. The terminations are 100% tin-plated copper, ensuring reliable solderability per MIL-STD-202 Method 208.
Typical applications include wireless base stations, network equipment, and telecom equipment where space-constrained, surface-mount protection is needed. The 045901.5UR is supplied in tape and reel packaging with a standard quantity of 500 pieces per reel.
