045202.5MR Description

Short technical summary and product information.

The Littelfuse 045202.5MR is a surface mount slow blow fuse from the NANO2 Slo-Blo series. It is rated for 2.5A and 125VAC/VDC, with a breaking capacity of 50A at rated voltage. The fuse features a slow blow response time, making it suitable for circuits with inrush currents that would cause fast-acting fuses to nuisance open.

 

The melting I²t is 15 A²sec at 8ms, and nominal cold resistance is 0.045 Ohm. Designed for board mounting in a 2-SMD square end block package, it measures 6.10mm x 2.69mm x 2.69mm. The operating temperature range is -55°C to 125°C.

 

The fuse is RoHS compliant and Halogen Free, with agency approvals including CSA, PSE, and UR. It is commonly used in applications such as notebook PCs, LCD monitors, power supplies, and telecom systems.
