MF-FSML/X Series PPTC Resettable Fuses

Bourns expands its Multifuse® product line with 8 V and 6 V rated model MF-FSML/X series of low resistance surface mount polymer positive temperature coefficient (PPTC) resettable fuses. This series includes Ihold current ratings from 0.35 A to 1.75 A at the 8 V maximum rated voltage and Ihold current ratings from 2.0 A to 3.0 A at the 6 V maximum rated voltage.

Bourns’ low resistance conductive materials used in this series have post-trip resistance values as low as 0.05 Ω and initial resistance values as low as 0.003 Ω. Such low resistance values help boost the current-carrying capability of the devices. The Bourns model MF-FSML300/6-2 offers an industry-leading 3.0 A Ihold at 6 VDC in a tiny 0603 package. These devices have been designed to protect against both overcurrent and overtemperature events within the designated specifications.

The model MF-FSML/X series utilizes Bourns’ innovative freeXpansion™ design that increases the performance of the resettable fuse with higher hold currents (Ihold), higher maximum voltage ratings (Vmax), improved resistance stability, and smaller footprints. These products are RoHS compliant and UL/TUV recognized for safety requirements. They are produced in Bourns’ IATF16949-certified facility in Xiamen, China.
