Bourns' TCO mini-breaker devices undergo rigorous testing to meet AEC-Q200-listed stress tests.
Bourns, Inc. has introduced the AD and SD series of resettable miniature thermal cutoff (TCO) mini-breaker devices, which are the first TCO devices to be tested by Bourns to comply with AEC-Q200-listed stress tests. These advanced devices incorporate cutting-edge overtemperature protection technologies, making them well-suited for a wide range of applications including heaters, motors, cables, and components on printed circuit boards.
The AD and SD series also provide exceptional overtemperature protection for lithium-ion batteries found in notebook PCs, tablets, smartphones, and power banks. Featuring high current capabilities and low resistance (less than 4 mΩ), these devices are available in either a surface mount (SD) or axial-leaded/weldable (AD) package.
Additionally, both series offer the flexibility of choosing between a non-automatically resettable option (self-hold function) or an automatically resettable option (non-self-hold function) for the TCO device, providing tailored solutions to meet specific application requirements.
