Bourns MF-USML/X Series PPTC Resettable Fuses

The Bourns Multifuse Product Line is pleased to announce the introduction of the new 12 V rated Model MF-USML/X series of low resistance surface mount Polymer Positive Temperature Coefficient (PPTC) resettable fuses. The new series includes Ihold current ratings from 1.75 A to 5.5 A at the 12 V maximum rated voltage.

Bourns’ low resistance conductive materials used in this new product series have post-trip resistance values as low as 10 mOhms and initial resistance values as low as 1 mOhms. Such low resistance values help boost the current carrying capability of the devices. The new Bourns Model MF-USML550/12-2 can now achieve 5.5 A Ihold at 12 Vdc in a space-saving 1210 package.

The compact Model MF-USML/X series utilizes Bourns’ innovative freeXpansion™ design that increases the performance of the resettable fuse with:

  • Higher hold currents (Ihold)
  • Higher voltages (Vmax)
  • Improved resistance stability
  • Smaller footprints

 

Features

  • Surface mount packaging for automated assembly
  • Small footprint size (1210) and low profile for  space-constrained mobile applications
  • Ultra-low resistance
  • Higher voltage withstand
  • RoHS compliant* and halogen free**

 

Applications​

  • Li-ion battery pack protection
  • PC and server motherboard protection
  • Mobile phone battery and charging protection
  • USB port protection
  • Power port protection
  • Gaming console port protection

* RoHS Directive 2015/863, Mar 31, 2015 and Annex.
