044302.5DR Description

Short technical summary and product information.

The Littelfuse 044302.5DR is a 2.5A, 250VAC Slo-Blo (slow-blow) surface mount fuse from the 443 Series. It is designed for overcurrent protection in applications where temporary inrush currents are expected, allowing the fuse to pass without nuisance opening.

 

Key electrical specifications include a current rating of 2.5A, voltage rating of 250VAC, and a breaking capacity of 50A at 250VAC (100A at 125VDC, 500A at 60VDC). The nominal cold resistance is 0.035 Ω, with a nominal melting I²t of 18.13 A²s and a voltage drop of 139 mV. The operating temperature range is -55°C to 125°C.

 

The fuse is housed in a compact 2-SMD, square end block package measuring 10.10mm x 3.12mm x 3.12mm, suitable for surface mount assembly. It is RoHS compliant, halogen-free, and compatible with lead-free solder processes.
