Overtemperature/overcurrent threats are growing concerns in higher capacity batteries that have greater stored energy. Short circuits or deep discharges can increase temperatures in the battery cell to levels high enough to cause damage not only to the battery cell itself, but to other components. Learn how miniature resettable Thermal Cutoff devices (TCO) or mini-breakers meet today’s denser, higher current battery protection needs with features like higher resistance values and operating currents along with improved temperature sensing.
