Miniature resettable thermal cutoff devices

23 October 2019 Circuit & System Protection

A new addition from Bourns is the Model CB series of miniature resettable thermal cutoff (TCO) devices. These are the smallest TCO devices Bourns has produced and represent the company’s next generation of axial leaded miniature resettable thermal cutoff devices.

The new CB series follows the successful NR series; it is about 26,5 % smaller than the NR series and 64,8 % smaller than the HC Series, yet it does not compromise current carrying capability. With resistance levels as low as 2,2 mΩ, the CB series can carry the same level of current as its larger counterparts in the HC and NR Series.

The CB series is available in four trip temperature options of 72°C, 77°C, 82°C and 85°C with a ±5°C tolerance. This can be further narrowed upon request. It has current capabilities from 6 A up to 11 A at 60°C and a welding projection option. The very low-profile height of 0,8 mm and body width of 2,5 mm make this series ideal for smaller batteries in smartphones and portable electronics, yet its high current carrying capability means it will be suitable for next-generation notebook PC and tablet battery cells.
