Each thermistor probe starts out as a chip that is then encapsulated in either glass or epoxy.
Depending on the application, this bead thermistor is then potted in a metal or plastic housing that is customized according to very specific requirements.

When used with an application such as lithium-ion battery, a thermistor probe with a ring lug can be easily mounted securely to the battery terminal. This thermistor probe can then effectively monitor the battery temperature.
