Bourns Expands High Temperature PTC Resettable Fuses

Bourns, Inc., a leading manufacturer and supplier of electronic components for power, protection, and sensing solutions, announced the Company has expanded its Multifuse® Model MF-USHT Surface Mount PPTC Resettable Fuse Series with nine new 125C high temperature products.

These latest additions are AEC-Q200 compliant and broaden the hold current (I_hold) range up to 2.0 A and increase the maximum voltage (V_max) to 36 VDC while raising the maximum operating temperature up to +125 °C.

The new fuses within the Model MF-USHT Series employ Bourns’ innovative freeXpansion™ technology, which enhances the product’s performance by incorporating higher hold currents, elevated voltages, and greater resistance stability all in a more compact footprint. These advanced features are particularly well-suited for overcurrent and overtemperature protection in electronic equipment that need to operate at high temperatures.

The nine new part numbers added to the Bourns® Model MF-USHT Series PPTC Resettable Fuse family are available now and are RoHS* compliant. In addition, the products are UL/CSA/TÜV recognized to meet safety criteria. The TÜV certifications also cover certifications for IEC 62319-1 and IEC 60738-1, as well as IEC 60730-1:2013 clause 15, clause 17, and Annex J. These products are manufactured within a Bourns IATF 16949 certified facility.
