TE Connectivity Unveils Resettable Thermal Cut-Off Devices for Lithium Battery Protection

In response to specific demands by designers and battery manufacturers, TE Circuit Protection has launched the MHP-TA series of ultra-low-profile resettable thermal cut-off (TCO) devices for lithium battery protection.

Measuring 5.8, 3.75 and 1.15 mm in length, width and height, respectively, the MHP-TA series of devices consists of two product categories having varied levels of current-carrying capacity, a 9 V dc rating, and multiple cut-off temperature ratings.

The MHP-TA series is built on the innovative MHP (Metal Hybrid PPTC) technology of TE Circuit Protection. This technology integrates a bimetal protector in parallel with a polymeric positive temperature coefficient (PPTC) device. The MHP30-36 and MHP-SA series that represents the initial MHP product offerings are effective for higher-current (over 30 V dc, 30 A) Li-ion battery pack applications adopted in portable energy storage systems and power tools.
