Silicon temperature sensors KTY82-2 series
DESCRIPTION
The temperature sensors in the KTY82-2 series have a
positive temperature coefficient of resistance and are
suitable for use in measurement and control systems.
The sensors are encapsulated in the small plastic SMD
SOT23 package.
Tolerances of 0.5% or other special selections are
available on request.

Notes
1.The thermal time constant is the time taken for the sensor to reach 63.2% of the total temperature difference.
For example, if a sensor with a temperature of 25 ° C is moved to an environment with an ambient temperature of
100 ° C, the time for the sensor to reach a temperature of 72.4 ° C is the thermal time constant.
2.Inert liquid, e.g. FC43 manufactured by the 3M company.
