Bourns SC Series Miniature Resettable TCO devices

Bourns is pleased to announce the release of the Model SC Series Miniature Resettable Thermal Cutoff (TCO) devices. These are Bourns' next generation of surface mount miniature resettable thermal cutoff devices, following the successful SA Series.

Miniature resettable thermal cutoff devices traditionally have been used in battery packs that use welding for assembly. However, the new SC series opens these circuit protection devices to multiple new applications as they can be reflow soldered onto printed circuit boards.

The new SC series features current capabilities from 5.5 A up to 8 A at 60 °C and is available in two height options. The very low profile SCxxAAB option has a height of just 0.94 mm ± 0.05 mm and the reinforced SCxxAAA option, at 1.07 mm ± 0.05 mm is designed to withstand the high injection molding pressures commonly experienced during USB cable manufacturing. The SC series is also designed to withstand humid environments and employs a high corrosion resistance bimetal mechanism.

The primary application for these devices is battery cell protection in smartphones and USB 3.1 type C cables.
