Silicon temperature sensors KTY84-1 series
DESCRIPTION
The temperature sensors in the KTY84-1 series have a
positive temperature coefficient of resistance and are
suitable foruse in measurement and control systems over
a temperature range of −40 to +300 °C. The sensors are
encapsulated in the SOD68 (DO-34) package. The leads
are nickel plated.
Tolerances of 0.5% or other special selections are
available on request.
The black band indicates the negative connection.
The marking provides type identity.
The sensor must be operated with the lower potential at the
marked connection.

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.
