SC Mini-Breakers (Miniature Thermal Cutoff Device)

Bourns SC Mini-Breakers are surface-mount miniature resettable Thermal Cutoff (TCO) devices. These mini-breaker devices feature current capabilities from 5.5A up to 8A at 60°C and are available in two height options. The low-profile SCxxAAB version offers a height of just 0.94mm ±0.05mm, whereas the reinforced SCxxAAA version is at 1.07mm ±0.05mm height. This design of the Bourns SC series helps to withstand the high injection molding pressures experienced during USB cable manufacturing.
