Mini-Breakers (Thermal Cutoff Devices)

Bourns Mini-Breakers (Thermal Cutoff Devices) feature a low or high current type and overtemperature / overcurrent protection for lithium polymer and prismatic cells. These devices also control abnormal, excessive currents instantaneously. Bourns Mini-Breakers are RoHS compliant and halogen free. The modules provide a robust and complete alternative for the protection of lithium cells in a compact, single-package solution.
