Product Description
Jingwo Technology's WSFB series three-terminal fuses integrate the fuse element and heating element into a single unit. Overcurrent or overvoltage triggers the heater to melt, ensuring reliable disconnection of lithium battery packs. The WSFB1512 has a rated current of 15A, is designed for 3 series cells, supports a maximum voltage of 36V DC, offers a breaking capacity of 50A, operates within 7.4–13.8V, features a heater resistance of 5.5–8.4Ω, and a fuse resistance of 1.0–3.0mΩ. With fast response times, it is ideal for high-density surface mounting and complies with RoHS standards.
