Bourns® Multifuse® PPTC Resettable Fuses

Almost anywhere there is a low-voltage power source and a load, a Multifuse® PPTC  Resettable Fuse can be used. The fact that these protection devices reset automatically sets them apart among circuit protection devices. Circuit designers know there are circumstances they have no control over which can result in potentially damaging overcurrent conditions.

  • Surface Mount (SMD), Radial Leaded (Through hole) and Axial Leaded (Strap) package options
  • Unlike one-time fuses, PPTCs do not need to be replaced
  • Overentcurrent events will not shut down the system
  • Fewer service calls mean lower warranty costs and better product quality
  • Avoids possible damage to the circuit by incorrect fuse replacement
