SC Series Miniature Resettable Thermal Cutoff Devices

Bourns® devices are the next generation of surface-mount miniature resettable thermal cutoff devices

Image of Bourns SC Series Miniature Resettable Thermal Cutoff (TCO) DevicesBourns model SC series miniature resettable thermal cutoff (TCO) devices are the 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 SC series opens these circuit protection devices to multiple additional applications as they can be reflow soldered onto printed circuit boards.

The 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.

Features
