Bourns New Miniature Resettable Thermal Cutoff Device Offers Highest Current Capacity

Bourns, Inc., a leading manufacturer and supplier of electronic components, today introduced 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.
