DESCRIPTIONS

The ATH100K1R25 series thermistor consists of three

versions, ATH100K1R25 as shown in Figure 1.1,

ATH100K1R25T70 shown in Figure 1.2 and

ATH100K1R25T70S. 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.
