049402.5NR Description

Short technical summary and product information.

The Littelfuse 049402.5NR is a board mount fuse designed for overcurrent protection in compact electronic circuits. It is rated for 2.5A continuous current with a voltage rating of 32V AC/DC. The fuse features a fast blow response time, making it suitable for protecting sensitive components that cannot tolerate sustained overcurrent conditions.

 

This fuse is housed in a standard 0603 (1608 metric) surface mount package, measuring 1.60mm x 0.81mm x 0.31mm. It is designed for automated assembly and is compatible with reflow soldering processes. The operating temperature range spans from -50°C to 90°C, allowing use in a wide variety of environments.

 

The breaking capacity at rated voltage is 35A, and the melting I²t is 0.144 A²s. The fuse carries CSA and UR safety approvals. It is intended for use in applications where fast-acting overcurrent protection is required in a small footprint.
