The 157T Series Fuse/Clip assembly is a small, square, time lag, surface mount fuse that is assembled in surface mountable fuse clips. The unique time delay feature of this fuse design helps solve the problem of nuisance "opening" by accommodating inrush currents that normally cause a fast acting fuse to open.

The fuse clip and pre-installed fuse combination can be automatically placed in PC Board in one efficient manufacturing operation. It permits quick and easy replacement of fuses without performing desoldering process, even in the field and without exposing the PC Board to detrimental effects of rework solder heat.

Features:
  • Surface Mountable, Time Lag Fuse
  • Fully compatible with RoHS/Pb-Free solder alloys and higher temperature profiles associated with leadfree assembly
  • Easily replaceable on PC Board (Field Replaceable)
  • RoHS Compliant
  • Available in ratings of 0.375 ~ 5 Amperes


  • Applications:
  • Instrumentation
  • Base Stations
  • Telecommunications
