MF-USML PPTC Resettable Fuses

Bourns MF-USML PPTC Resettable Fuses offer a maximum operating current from 1.75A to 7A, resistance values as low as 13.5mΩ, and initial resistance values as low as 1mΩ. These low resistance values help boost the current carrying capability of these devices. The compact MF-USML models use Bourns freeXpansion™ design that increases the performance of the resettable fuse with higher hold currents, higher voltages, improved resistance stability, and smaller footprints. The 1210 footprint with a low profile is ideal for space-constrained mobile, and the surface-mount packaging is suitable for automated assembly. Typical applications for Bourns MF-USML PPTC Resettable Fuses include PC motherboard port protection, USB memory modules, wearable devices, and battery protection for smartphones.
