Resettable thermal cutoffs

31 January 2017 Circuit & System Protection

Bourns announced the release of the Model AA Series miniature resettable thermal cutoff (TCO) devices, which effectively deliver higher current over-temperature protection to make newer battery designs more reliable by controlling specified abnormal, excessive current virtually instantaneously.

The product range offers as much as 37% more current capacity compared to Bourns’ previously available miniature resettable TCOs and is capable of carrying 14 A at 60°C. It also delivers the impedance/resistance a full 60% lower than earlier generation devices.

Many designs that previously needed two miniature resettable thermal cutoff devices to provide ample higher capacity protection, can be achieved through the use of a single Model AA device due to the innovative design and high-precision metal process.
