Littelfuse Surface-Mount Time-Delay Fuse

DES PLAINES, IL – Littelfuse, Inc. (NASDAQ/NGS:LFUS) today introduced its 0443 surface mount time-lag fuse line for overcurrent protection of printed circuit boards.

With dimensions of approximately 10.1 x 3.12 x 3.12 mm, these fuses are ideal for applications with the higher 250 VAC requirement and where space is limited.


They have inrush current withstand (I2t) ratings of up to 127A2s (5A current rating) along with a time lag characteristic. This means lower probability the fuse will open during momentary overloads, which can add up to lower warranty board replacement costs.


The small size characteristic of the 0443 Series was designed to be particularly attractive to OEMs of products that have AC inputs for LED lighting, notebook PC power adapters, or any AC/DC power module.


The 0443 Series offers current ratings from 500mA to 5A, all with an interrupting rating of 50A at 250VAC.


This product series complements Littelfuse’s broad line of DC surface mount fuses used on the secondary side of power circuits, with ratings from 62mA to 15A at voltages from 24 to 350VDC.
