The ATH10KR8B is a series of high precision glass encapsulated ntc thermistor. The ATH10KR8B series ntc thermistor come with three versions, ATH10KR8B, ATH10KR8BT65 and ATH10KR8BT65S. The ATH10KR8B has two bear leads coated with copper; the ATH10KR8BT65S has the two leads covered with high temperature plastic tubing and sealed by epoxy, while the ATH10KR8BT65 is the non-sealed version with plastic tubing. They can work under up to 140°C temperature and the latter is of liquid resistant.
Comparing with conventional epoxy encapsulated thermistors, ATH10KR8B presents higher long term stability and wider temperature range. In addition, it comes with a compact size and short response time.
The ATH10KR8B series can be applied to measure the temperatures for laser diodes, optical components, etc., with high accuracy and long term stability.
This thermistor ATH10KR8B is a replacement for ATH10KR8. The parameters are shown as below.
