RIVERSIDE, Calif., January 13, 2025 - Bourns, Inc., a leading manufacturer and supplier of electronic components for power, protection, and sensing solutions, today announced the Company has expanded its Multifuse® Model MF-USHT Surface Mount PPTC Resettable Fuse Series with nine new 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.
