0454.750MR Description

Short technical summary and product information.

The Littelfuse 0454.750MR is a NANO2 Slo-Blo surface mount fuse from the 452/454 Series. It is rated for 750mA (0.75A) at 125VAC/VDC with a breaking capacity of 50A at rated voltage. The slow blow (time-delay) response accommodates inrush currents that would cause fast-acting fuses to open, reducing nuisance opening.

 

Electrical characteristics include a melting I²t of 0.904 A²sec and a nominal cold resistance of 0.360 ohms. The fuse operates over a temperature range of -55°C to 125°C. It is packaged in a 2-SMD square end block case measuring 6.10mm x 2.69mm x 2.69mm and is designed for surface mount assembly.

 

The 0454.750MR is recognized by UL (File E10480) and CSA (File 29862), and carries CE and UKCA marks. It is RoHS compliant and halogen free, suitable for use in notebook PCs, LCD displays, power supplies, networking equipment, telecom systems, battery charging circuits, and industrial equipment.
