Bourns Announces the Release of New Miniature Resettable Thermal Cutoff Devices Model AA Series

2017-01-03 | Return

Riverside, California - January 3, 2017 - Bourns is pleased to announce the release of the Model AA Series Miniature Resettable Thermal Cutoff (TCO) devices. The Model AA Series effectively delivers higher current overtemperature protection to make newer battery designs more reliable by controlling specified abnormal, excessive current virtually instantaneously.

The Bourns® Model AA Series 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. The Model AA Series delivers the lowest impedance/ resistance – a full 60 % lower than earlier generation Bourns® TCO devices.

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