015401.5DRT Description

Short technical summary and product information.

The Littelfuse 015401.5DRT is a 1.5A, 125V Slow Blow (time-lag) board mount fuse designed for surface mount applications. It features a 2-SMD square end block package with an integrated holder, enabling easy fuse replacement without soldering. The fuse has a breaking capacity of 50A at rated voltage and a melting I²t of 3.65 A²s.

This component is part of the 154 Series OMNI-BLOK fuse and holder assembly, which combines a Nano2 surface mount fuse with a holder for efficient PC board installation. It is RoHS compliant and halogen-free, with a wide operating temperature range of -55°C to 125°C. The fuse is recognized by PSE and UL agencies.

Designed for overcurrent protection in a variety of electronic circuits, the slow blow characteristic allows it to withstand temporary inrush currents without nuisance opening, making it suitable for applications with capacitive or inductive loads.
