High energy density battery protection announced

Bourns’ new Model NX Series miniature resettable thermal cutoff (TCO) device is designed to offer higher current-carrying capabilities combined with a low-profile package measuring 0.94 by 2.8mm. These features make this series an ideal overtemperature and overcurrent protection solution for lithium polymer and prismatic cells in high energy density, smaller batteries such as next-generation notebook PC and tablet battery cells, plus handheld and wearable electronics.

Bourns Thermal & Precision Division’s VP of products and technology, Brian Ahearne, said: “While our new Model NX Series has the same footprint as our Model NR series, it can carry 40 per cent more current. This is the result of numerous design advancements including the use of new high conductivity electrode materials. These features enable customers to shrink the size of their product and still maintain an elevated level of overtemperature and overcurrent protection that enhances their product reliability and safety.”

The Series has current capabilities from 12 to 20A at 60°C.
