New Multifuse® Polymer PTC Resettable Fuses deliver enhanced design flexibility and offer increased power ratings in a compact 1206 package size

RIVERSIDE, Calif., December 18, 2023 - Bourns, Inc., a leading manufacturer and supplier of electronic components for power, protection, and sensing solutions, today announced the addition of 20 new part numbers to its Multifuse® Polymer PTC Resettable Fuse line. Bourns designed these new higher power rated fuses to give customers greatly expanded overcurrent/ overtemperature protection selection options in a smaller 1206 footprint. This smaller footprint allows customers to meet smaller board space requirements that can also help them reduce costs. These smaller package alternatives will also help designers meet various requirements such as for 16 V_max. For instance, these fuse models in the 1206 package size give designers a 67 percent board space savings compared to the Bourns® Model MF-NSMF110/16-2 in the 1812 package size.

The latest additions to the Model MF-NSMF Series showcase Bourns’ innovative freeXpansion™ technology that increases the performance of the fuse with the ability to handle higher currents and voltages, improves its resistance stability and allows for a smaller footprint. On top of the expanded design selection options that range from 14 to 34 choices, the new fuses feature a broad range of hold current (I_hold) options, extending from 0.05 A to 2.0 A and multiple elevated rated Voltage (V_max) options, from 6 VDC to 60 VDC. These enhancements are particularly well-suited to provide highly reliable overcurrent and overtemperature protection while remaining well within specified product parameters in low DC voltage ports such as those commonly found in USB, HDMI, HDTV, PCs, laptops, data centers, and portable consumer electronics.

The 20 new Bourns® Multifuse® MF-NSMF family part numbers are available now. These models are RoHS compliant* and halogen free**. For more detailed product information, please see: www.bourns.com/products/circuit-protection/resettable-fuses-multifuse-pptc#smdss.
