MF-NSML/X Series 12 V Rated Low Resistance PPTC Re

The Bourns Multifuse® product line's 12 V rated Model MF-NSML/X series of low resistance surface mount polymer positive temperature coefficient (PPTC) resettable fuses includes IHOLD current ratings from 1.5 A to 4.5 A at the 12 V maximum rated voltage.

Bourns' low resistance conductive materials used in this product series exhibit post-trip resistance values as low as 14 mΩ and initial resistance values as low as 2 mΩ. Such low resistance values help boost the current carrying capability of the devices. The Bourns model can now achieve 4.5 A IHOLD at 12 VDC in a space-saving 1206 package (Model MF-NSML450/12-2).

The compact MF-NSML/X model family utilizes Bourns' innovative freeXpansion design, increasing the performance of the resettable fuse with higher hold currents (IHOLD), higher voltages (VMAX), improved resistance stability, and smaller footprints.

The primary applications for these products include Li-ion battery packs, motherboards, and portable consumer electronic I/O port protection. These devices have been designed to protect against both overcurrent and overtemperature events within the products' designated specifications.

The Model MF-NSML/X Multifuse PPTC products are RoHS compliant and UL recognized for safety requirements, and are produced in Bourns' IATF16949 approved facility in Xiamen, China.
