WSFB1508
TLCET WSFB1508 three-terminal fuse (2-cell Li-ion protection)
WSFB series three-terminal fuse rated 15A and 36V DC maximum, for 2-cell Li-ion packs, integrating overcurrent and overvoltage cutoff.
- Three-terminal SMD
- Notebook, tablet, vacuum cleaner and power tool battery packs
- TLCET three-terminal fuses
Product description
TLCET WSFB series three-terminal fuses integrate the fuse element and heater; on overcurrent or overvoltage the heater triggers the fuse to reliably open the Li-ion pack. The WSFB1508 is rated 15A for 2-cell packs, 36V DC maximum, 50A breaking capacity, 5.0–9.0V operating voltage, heater resistance 2.2–3.3Ω and fuse element resistance 1.0–3.0mΩ, with fast response for high-density SMT and RoHS compliance.
