The
ATH100K1R25 is a high precision and glass encapsulated NTC thermistor with high stability. This
NTC thermistor can be applied for temperature sensing for laser diodes, optical components, temperature control system, industrial process control, etc. All these applications require high temperature sensitivity, long term stability, and/or high sensing temperature.
This NTC thermistor is the same as
ATH10K1R25 on its size and dimension. The thermistor head is φ1.25mm×2.0mm. The length of its two leads is 70 ± 1mm with a diameter of 0.2mm. The nominal resistance at 25°C is 100K ± 1%.
This thermistor has a wide temperature range, from −40°C to 270°C. They can work under up to 140°C temperature. In order to meet different requirements, there are two more versions besides bare leads thermistor: ATH100K1R25T70 and ATH100K1R25T70S. The former has two leads covered with high temperature plastic tubing and the latter does the same, but has its thermistor head and the plastic tubing sealed. The sealed version is liquid resistant, which can be used in liquid.
