SFLT Series Strap Resettable PTC Fuses

Semifuse SFLT series re-settable PTC fuses from Fuzetec offer improved battery protection, particularly in low-power battery applications.  These strap format PTC fuses provide reliable non-cycling protection against battery short-circuits or over-charging.

The SFLT series PTCs switch at lower temperatures than other PTC series (SFSR), therefore giving them faster trip times and making them ideal for the latest generation of lower-power battery designs.  Due to their lower trip temperatures, care must be taken in specifying the correct PTC for the given battery design.
