0449002.MR Description

Short technical summary and product information.

The Littelfuse 0449002.MR is a 2A board mount fuse designed for overcurrent protection in surface mount applications. It is rated for 125VAC and 125VDC with a breaking capacity of 50A at rated voltage. The slow blow (time-delay) characteristic allows the fuse to tolerate temporary inrush currents without nuisance opening, making it suitable for circuits with capacitive or inductive loads.

 

This 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 melting I²t value is 6.76, providing predictable performance under fault conditions.

 

Approvals include cULus and PSE, indicating compliance with North American and Japanese safety standards. The surface mount design enables automated assembly, reducing manufacturing costs.
