High-Power PPTC Resettable Fuses - MF-LSMF Series

Bourns' Multifuse® product line expands its model MF-LSMF series high-power surface-mount polymeric positive temperature coefficient (PPTC) resettable fuses. These models expand the hold current range from 0.75 A ~ 6.0 A with maximum voltages of 6 V_DC ~ 60 V_DC and 20 additional options available.

The MF-LSMF family utilizes Bourns’ innovative freeXpansion™ design to increase the performance of the resettable fuse with higher hold currents (I_hold), higher voltages (V_max), 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.
