Bourns CB Series Resettable Thermal Cutoff Devices

Bourns is pleased to announce the introduction of its new Model CB Series of miniature resettable thermal cutoff(TCO) devices.These are the smallest TCO devices Bourns has produced and they are the next generation of axial leaded miniature resettable thermal cutoff devices.

The new Model CB Series follows the successful Model NR Series and 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 mO, the CB Series can carry the same level of current as its larger counterparts in the HC and NR Series.

The Bourns® Model 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.The Model CB Series 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 makes this series ideal
for smaller batteries in smartphones and portable electronics, yet the high current carrying capability means these miniature devices will be suitable for next generation notebook PC and tablet battery cells.

These devices have been designed to withstand humid environments and use a high corrosion resistant bimetal mechanism.
