015403.5DRTL Description

Short technical summary and product information.

The Littelfuse 015403.5DRTL is a 3.5A, 125V Slow Blow (time-lag) surface mount fuse from the 154TL Series OMNI-BLOK Fuse and Holder Assembly. This component integrates a Nano2 fuse with a holder in a single tape and reel package, enabling efficient PC board installation and easy fuse replacement without exposing the board to solder heat.

 

Key electrical specifications include a nominal current rating of 3.5A, a voltage rating of 125V, and a breaking capacity of 50A at rated voltage. The fuse has a melting I²t of 26.53 A²s and a Slow Blow response time, making it suitable for applications with inrush currents. It is approved by PSE and UL.

 

The fuse is housed in a 2-SMD, square end block package with holder, measuring 9.73mm x 5.03mm x 3.81mm. It requires a holder for surface mount installation. The operating temperature range is -55°C to 125°C, and the holder is made of heat-resistant UL94 V-0 material, capable of withstanding 260°C reflow profiles.
