0452001.MRL Description

Short technical summary and product information.

The Littelfuse 0452001.MRL is a 1A, 125V surface mount fuse from the NANO2 Slo-Blo series (452 series). It is designed to withstand high inrush currents without nuisance opening, making it suitable for applications where fast-acting fuses would prematurely open. The fuse offers a slow blow response time with a breaking capacity of 50A at rated voltage.

 

Key electrical specifications include a nominal cold resistance of 0.225 Ω and a melting I²t of 1.98 A²sec. The fuse is housed in a compact 2-SMD square end block package measuring 6.10mm x 2.69mm x 2.69mm. It operates over a wide temperature range of -55°C to 125°C.

 

The component holds agency approvals from CSA, PSE, and UR, and is RoHS compliant and halogen free per the datasheet. Suitable for board-level overcurrent protection in power supplies, networking equipment, LCD displays, and industrial equipment.
