DESCRIPTION
The ATH10KR8 is a high precision glass encapsulated
thermistor. Comparing with conventional epoxy encapsulated
thermistors, ATH10KR8 presents higher long term stability
and wider temperature range. In addition, it has a small size
and short response time.
The ATH10KR8 can be used to measure the temperatures for
laser diodes, optical components, etc., with high accuracy and
long term stability.

APPLICATION
Drill a hole on the object for which the temperature needs to
be measured and use thermally conductive epoxy to pot the
thermistor inside the hole. The hole diameter should be
between 1.2 to 1.4mm and the depth should between 2 to
2.5mm. When a deeper hole is needed, drill a 2 stage hole to
prevent mounting epoxy bobbles trapped inside which would
cause temperature measurement errors. Figure 2 shows the
section view of the 2 stage hole.

The worst mounting result is that there are air bubbles
trapped inside the thermistor mounting hole. These bubbles
cause thermal sensing time delay and sensing temperature
errors. To avoid the bubbles, use thin epoxy, vibrate the
assembly before curing, and cure the epoxy inside the
mounting hole at high temperature, 80°C to 150°C,
depending on the epoxy used and the maximum temperature
assembly components allow.
The thermistor lead wires are made of plain copper and there
is no insulation coating on them, please make sure that they
do not touch each other after mounting the thermistor.
Some thermal conductive epoxies are also electrically
conductive and such epoxies should not be used for mounting
the thermistors, since the lead wires are conductive.
