Bourns MF-LSMF series high power PPTC resettable fuses

The Bourns is pleased to announce the expansion of its model MF-LSMF series high power surface mount polymeric positive temperature coefficient (PPTC) resettable fuses. The new models expand the hold current range to 0.75A to 6.0A with maximum voltages of 6VDC to 33VDC and twenty options available. The latest MF-LSMF model family utilizes Bourns’ innovative freeXpansion™ design to increase 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, low voltage telecom equipment, motherboards and portable consumer electronics protection. These devices have been designed to protect against both overcurrent and overtemperature events within the designated product specifications.
