Bourns MF-USML Series PPTC Resettable Fuses offer maximum operating current from 1.75A to 7.0A, resistance values as low as 13.5mΩ, and initial resistance values as low as 1mΩ.
Bourns’ low ohmic materials used in this product family have post trip resistance values as low as 13.5 mOhms and initial resistance values as low as 1 mOhm. Such low resistance values help boost the current carrying capability of these new devices. Bourns can now achieve a 7 A Ihold model in a 1210 package (MF-USML700-2).
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 primary applications for these products include PC motherboard port protection, USB memory modules, wearable devices and battery protection for smart phones. These devices have been designed to protect against both overcurrent and overtemperature events within these applications.
