Miniature Resettable Thermal Cutoff Device Offers Highest Current Capacity

RIVERSIDE, CA - Bourns, Inc. introduces a breakthrough miniature resettable thermal cutoff (TCO) device series delivering the highest current capacity for comparable devices, matching the protection needs of today’s denser, higher capacity Lithium Ion (Li-Ion) battery cells. The new Model AA Series is capable of carrying 14 A at 60 °C, offering as much as 37 % more current capacity compared to Bourns’ previously available miniature resettable TCOs.

The new protection devices also deliver extremely low impedance/resistance (2 mΩ max.), which is 60 % lower than earlier generation TCOs from Bourns. Saving costs and valuable design space, 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.

Pricing and Availability

The Model AA Series from Bourns is available now. As a pricing reference, Model AA72A10 is priced at $0.73 each in 3,000 piece quantities.
