Bourns AC Mini TCO (Thermal Cutoff) Devices
Bourns AC Mini TCO (Thermal Cutoff) Devices effectively deliver higher current overtemperature protection in five trip temperature options from +72°C to +90°C. The series makes newer battery designs more reliable by controlling specified abnormal excessive current virtually instantaneously. These protection devices deliver extremely low impedance/resistance (2mΩ max.). The series is engineered to help battery pack designers save design space and weight by being 0.12mm thinner and 16% lighter than the existing Model AA series. Bourns AC Mini TCO (Thermal Cutoff) Devices are ideal for notebook PCs, tablet PCs, and smartphones.Features
