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. In addition, there are two insulation versions available, one of which comes with leads covered by plastic tubing, the ATH100K1R25T70, and the other one, the ATH100K1R25T70S, is sealed between the head and the tubing. They can work under up to 140°C temperature and the latter is of liquid resistant.

The ATH100K1R25 series thermistors can be used to sense the temperatures for laser diodes, optical components, industrial process control, etc., where high temperature sensitivity, long term stability, and/or high sensing temperature are required.
