Bourns Announces the Release of New Miniature Resettable Thermal Cutoff Devices Model AC Series
2018-04-19 | ReturnRiverside, California - April 19, 2018 - Bourns is pleased to announce the release of the Model AC Series Miniature Resettable Thermal Cutoff (TCO) devices. The Model AC 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 AC Series offers five trip temperature options from 72 °C to 90 °C, making it the highest current-carrying TCO device Bourns offers. The new protection devices deliver extremely low impedance/resistance (2 mΩ max.). The new AC Series is designed to help battery pack designers save valuable design space and weight. To achieve this, the AC Series is 0.12 mm thinner and 16 % lighter than the exisiting Model AA Series. Model Specifications Trip Temperature Resistance AC72ABD 72 °C ± 5 °C 2 milliohms max. (1 ~ 1.5 milliohms typical) AC77ABD 77 °C ± 5 °C AC82ABD 82 °C ± 5 °C AC85ABD 85 °C ± 5 °C AC90ABD 90 °C ± 5 °C
Features
。Miniature Thermal Cutoff (TCO) device
。High current capacity, low impedance
。Wide range of temperature options
。Overtemperature and overcurrent protection for lithium polymer and prismatic cells
。Controls abnormal, excessive current virtually instantneously, up to rated limits
Applications
Battery cell protection for:
。Notebook PCs
。Tablet PCs
。Smart phones
