Eaton presents their SCF series of self-control, triggerable fuses. These multi terminal fuses provide both overcurrent and overcharging protection for single and multi-cell battery applications . An integrated thermal element provides triggerable operation from an external FET or IC during an overcharge condition and a traditional fusible element offers fast-acting performance for short circuit protection. The SCF fuses are available in three different surface mount packages where the SCF4030, the SCF5432, and SCF9550 support up to 10, 14, and 24 applicable cells in series. The fuses are both RoHS-compliant and halogen-free with current ratings from 12 amps up to 45 amps and operational voltages up to 80 VDC. The self-control fuses are suitable for battery-powered electronics such as notebook and laptop computing, handheld electric power tools, and battery powered household appliances.
