Product description
TLCET WSFB series three-terminal fuses integrate the fuse element and heater in one device; on overcurrent or overvoltage the heater triggers the fuse to reliably open the Li-ion pack. The WSFB1208 is rated 12A for 2-cell packs, 36V DC maximum, 50A breaking capacity, heater resistance 2.0–3.2Ω and fuse element resistance 1.5–3.5mΩ, with fast response for high-density SMT and RoHS compliance.
