The ATH100K1R25 series thermistor consists of three versions. The ATH100K1R25 has bear leads coated with copper, the ATH100K1R25T70S has the leads covered by high temperature plastic tubing and sealed by epoxy, while the ATH100K1R25T70 is the non-sealed version.

The ATH100K1R25 is of a high stability and high precision glass encapsulated thermistor. Comparing with conventional epoxy encapsulated thermistors, ATH100K1R25 features much wider temperature range, especially on the high end, much better long term stability, smaller size, and shorter response time.
