DESCRIPTIONS

The ATH10K1R25 series thermistor consists of three versions,

ATH10K1R25 as shown in Figure 1.1, ATH10K1R25T70

shown in Figure 1.2 and ATH10K1R25T70S. The

ATH10K1R25 has bare leads coated with copper, the

ATH10K1R25T70S has the leads covered by high temperature

plastic tubing and sealed by epoxy, while the

ATH10K1R25T70 is the non-sealed version.

The ATH10K1R25 is of a high stability and high precision

glass encapsulated thermistor. Compared to conventional

epoxy encapsulated thermistors, ATH10K1R25 features a

much wider temperature range, especially on the high end,

much better long term stability, a smaller size, and a shorter

response time. In addition, there are two insulation versions

available, one of which comes with leads covered by high

temperature plastic tubing, the ATH10K1R25T70, and the

other one, the ATH10K1R25T70S, is sealed between the head

and the tubing. They can work under temperatures as high as

140°C and the latter is liquid resistant.

The ATH10K1R25 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 sensing high temperatures are required.

Figure 2, Figure 3 and Figure 4 show the mechanical

dimensions of the ATH10K1R25, the ATH10K1R25T70 and

the ATH10K1R25T70S respectively. All dimension units are

millimeters.
