MF-NSML/X PPTC Resettable Fuses

Bourns MF-NSML/X PPTC Resettable Fuses feature ultra-low resistance and utilize innovative freeXpansion™ design. These fuses offer a maximum voltage of 12V and a current of 50A. Bourns MF-NSML/X low ohmic PTC resettable fuses operate at a -40°C to +85°C temperature range. These resettable fuses come in a small footprint size (1206) and low profile for space-constrained mobile applications. These fuses are also ideal for power delivery port protection, USB port protection, and game console port protection.
