MF-USML/X Low Ohmic PPTC Resettable Fuses

Bourns MF-USML/X Series are resistance surface mount Polymer Positive Temperature Coefficient (PPTC) resettable fuses with a 12V rating. The low ohmic series utilizes Bourns freeXpansion™ design, which increases the performance of the resettable fuse with higher hold currents (I_hold), higher voltages (Vmax), improved resistance stability, and a smaller footprint. The fuses can now achieve 5.5A I_hold at 12V_DCand current ratings of 1.75A to 5.5A in a space-saving 1210 package. Model MF-USML/X fuses are ideal for Li-ion battery packs, motherboards, and portable consumer electronic I/O port protection. The series is designed to protect against both overcurrent and overtemperature events within the designated specifications.
