Product Description
Jingwo Technology's WSFB series three-terminal fuses integrate the fuse element and heating element into a single unit. The heater triggers the fuse during overcurrent or overvoltage events to reliably disconnect lithium battery packs. The WSFB1508 has a rated current of 15A, supports 2 cells in series, offers a maximum voltage of 36V DC, a breaking capacity of 50A, an operating voltage range of 5.0–9.0V, a heater resistance of 2.2–3.3Ω, 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 requirements.
