Thermal cut off devices used to prevent heat and fires caused by excess current

Available from Farnell element14, Bourns KOMATSULITE thermal cut off devices are used in batteries for such devices as notebook PCs, tablets, digital cameras, and smartphones. These devices are self-preserving, and designed to stay tripped (operated) during abnormal temperatures, and then recover when power is cut and the temperature returns to a safe level. This allows for protection at lower temperatures compared with polymer PTCs and temperature fuses used for the same applications. These devices have obtained UL and TUV safety standard certifications, and employ global environmental protection measures.
