Overvoltage protection in three designs

The battery protection with three terminals is excellently suited for surface mounting due to its flat and compact design and is ideal for single-cell and multi-cell battery packs. The SCFs protect against both overcurrent and overcharging. This makes them predestined for a wide range of uses in consumer, computer, power, industrial, home appliance, handheld, and medical applications, among others.

They are available in 4.0 x 3.0mm for a rated current range of 12 to 22A (SCF4030), 5.4 x 3.2mm for a rated current range of 12 to 30A (SCF5432) and 9.5 x 5.0mm for a rated current of 30 to 45A (SCF9550).

The Self-Control Fuse has an integrated heating element with fuse for IC/FET triggering capability that responds quickly to an unexpected cell or pack level overvoltage or overtemperature. For high efficiency in lithium-ion battery packs, the SCF series operates with a wide range of current ratings and low internal resistance. With this series, Eaton offers one of the most comprehensive portfolios of self-controlling fuses for series connections of up to 24 Lithium-ion battery cells.
