Bourns' TCO micro circuit breaker equipment passes the pressure tests listed in the AEC-Q200

The Bourns AD and SD series resetable Miniature thermal fuse (TCO) circuit breaker devices are the first class of Bourns TCO devices that have passed the pressure test of the AEC-Q200 standard. The AD and SD series' advanced overheating protection technology makes them ideal solutions for a wide range of applications such as heaters, motors, cables and printed circuit board components.

They also provide excellent overheating protection for lithium-ion batteries in laptops, tablets, smartphones and power banks. AD and SD are available in surface mount (SD) or axial lead/weldable (AD) packages with high current and low resistance (less than 4 mΩ). Both families offer options for either non-automatic reset (self-holding function) or automatic reset (non-self-holding function) for TCO devices
