Product description

SFK-4045A is a surface mounted fuses that achieves a 45 Amperes rating. This product is applicable to 9 to 10-cells series-connected battery packs. It protects lithium-ion batteries from overcharging (overvoltage) and overcurrent. When overcharged, the fuse element melts and cuts off the circuit upon receiving a signal from the secondary protection IC, and at the same time, the power supply to the heater is also shut off. By placing the heater directly below the fuse element, it demonstrates excellent cutoff characteristics.
