Abstract
The present disclosure provides high temperature thermal cutoff devices having a high-temperature thermal pellet with a transition temperature of greater than or equal to about 240° C. and comprising at least one organic compound. The pellet is disposed in a housing, which is sealed with a high-temperature seal that provides substantial sealing up to at least the transition temperature. The high-temperature TCO also has a current interruption assembly, which establishes electrical continuity in a first operating condition corresponding to an operating temperature of less than said transition temperature and discontinues electrical continuity when the operating temperature exceeds the transition temperature. Methods of making such high-temperature thermal cut off devices are also provided.
