ATH100K1R25 series ntc thermistors are high precision glass encapsulated thermistors with long term stability. Comparing with conventional epoxy encapsulated thermistors, ATH100K1R25 has a wider temperature range, especially on the high end applications, better long term stability, smaller size, and a shorter response time. Besides the bare leads, we provide two insulation versions. One is with the two leads covered by plastic tubing, and the part number is ATH100K1R25T70, and the other one, the ATH100K1R25T70S, is sealed between the thermistor head and the plastic tubing. All of the thermistors can work under up to 140°C temperature and the latter is liquid resistant. The main parameters are shown in the table below.
