Thermal Cutoff Overtemperature (TCO) Protection Devices - AD & SD Series
Bourns' TCO mini-breaker devices are tested to AEC-Q200-listed stress tests
AD and SD series resettable miniature thermal cutoff (TCO) mini-breaker devices from Bourns, Inc. are the first TCO devices tested by Bourns to AEC-Q200-listed stress tests. The AD and SD series' advanced overtemperature protection technologies make them ideal solutions for a broad variety of applications such as heaters, motors, cables, and printed circuit board components. They also offer excellent overtemperature protection for lithium-ion batteries in notebook PCs, tablets, smartphones, and power banks. The AD and SD feature high current and low resistance (less than 4 mΩ) in either a surface mount (SD) or axial-leaded/weldable (AD) package. Both series offer the option for the TCO device to be either non-automatically resettable (self-hold function) or automatically resettable (non-self-hold function).
