Bourns Mini-Breakers
Bourns Mini-Breakers are Thermal Cutoff (TCO) devices that are used as safety devices to help prevent heat and fires caused by excess current, mainly in lithium-ion batteries. The Mini-Breakers are self-preserving devices designed to stay tripped during abnormal temperatures, and then recover when power is cut, and the temperature returns to a safe level. These Mini-Breakers are UL and TUV certified, and provide a robust and complete alternative for the protection of lithium cells in a compact and single-package solution. The Mini-Breakers are ideal for various applications, including digital cameras, mobile phones, notebooks, PCs, and tablets.
