0154004.DRT Description

Short technical summary and product information.

The Littelfuse 0154004.DRT is a 4A, 125V board mount fuse from the 154 Series OMNI-BLOK family. It features a slow blow (time-lag) response characteristic suitable for applications with inrush currents. The fuse is rated for 50A breaking capacity at 125V and has a melting I²t of 34.4.

 

The 0154004.DRT is housed in a 2-SMD, square end block with holder package measuring 9.73mm x 5.03mm x 3.81mm (0.383" x 0.198" x 0.150"). The mounting type requires a holder for surface mount installation, enabling easy fuse replacement without exposing the PC board to solder heat.

 

This fuse carries approval from PSE and UL. It is both RoHS compliant and halogen-free, and operates over a temperature range of -55°C to 125°C. Cross-references include distributor part numbers F1309TR-ND (tape and reel), F1309CT-ND (cut tape), and F1309DKR-ND (Digi-Reel).
