Multifuse® PPTC Resettable Fuses - MF-NSHT and MF-USHT Series

Bourns expands the Multifuse product line with the MF-NSHT and MF-USHT series SMD high temperature resettable fuses

Image of Bourns' Model MF-NSHT and MF-USHT Series Multifuse® PPTC Resettable FusesBourns offers the MF-NSHT and MF-USHT series high temperature Multifuse polymer PTC resettable fuses. These 1206 and 1210 (3014 and 3024 metric) sized surface-mount devices join Bourns’ already successful MF-PSHT high temperature SMD series.

The innovative freeXpansion™ design high-temperature materials used in this product family operate up to +125°C and have been primarily designed for automotive applications; however, with the ongoing trend to increase board density in other areas such as industrial, telecom and consumer electronics, the operating temperature of some electronics is increasing. This makes the miniature size PPTC with an elevated operating temperature ideal for high-density boards.

The compact MF-NSHT and MF-USHT series use the freeXpansion design that increases the performance of the resettable fuse with:
  • Higher hold currents (Ihold): 100.0 mA to 2.0 A
  • Higher voltages (Vmax): 12 V to 36 V
  • Improved resistance stability
  • Smaller footprints
Features
  • Compliant with AEC-Q200 Rev-C-Stress Test
  • UL/CSA/TUV recognition
  • Qualification for Passive Components in Automotive applications
  • Small footprint size (1206 and 1210)
  • Operating temperature range up to 125°C
  • Low thermal derating factor
  • Higher hold currents at elevated temperatures
  • RoHS compliant

Applications

  • Protection of automotive circuitry including engine control modules
  • Overcurrent surge protection of electronic equipment required to operate at high operating temperature ranges
  • Resettable fault protection for general electronic equipment
