Silicon temperature sensors KTY83-1 series
DESCRIPTION
The temperature sensors in the KTY83-1 series have a
positive temperature coefficient of resistance and are
suitable for use in measurement and control systems.
The sensors are encapsulated in the SOD68 (DO-34)
leaded package.
Tolerances of 0.5% or other special selections are
available on request.
Fig.1 Simplified outline (SOD68; DO34).
The first (black) band indicates the negative connection.
The second (coloured) band provides type identity.
The sensor must be operated with the lower potential at the
marked connection.

CHARACTERISTICS
Tamb =25°C, in liquid, unless otherwise specified.
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.
