Bourns introduces a miniature resettable thermal cutoff (TCO) device series delivering 14-A current capacity, matching the protection needs of today’s denser, higher capacity Li-Ion battery cells. The Model AA Series can carry 14 A at 60 C, offering as much as 37 % more current capacity compared to the company’s previously available miniature resettable TCOs.
The protection devices also deliver 2 mΩ max. impedance/resistance, which is 60% lower than earlier generation TCOs from Bourns. The higher current Li-ion battery designs that previously needed two miniature resettable TCOs now only need a single AA series device to meet protection requirements due to the innovative design and high precision metal press process.
Today’s electronics such as e-bikes, power tools and even consumer robots and energy grid storage are seeing the benefits of a reduced battery pack cell count that ultimately cuts application costs.
The Model AA Series from is available now. As a pricing reference, Model AA72A10 is priced at $0.73 each in 3,000 piece quantities. For more information on these latest miniature resettable TCO devices, please go to: www.bourns.com/products/circuit-protection/mini-breakers
