Product data sheet
1. Product profile
1.1 General description
The temperature sensors in the KTY84 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) package.
Other special selections are available on request.
CAUTION
This device is sensitive to ElectroStatic Discharge (ESD). Therefore care should be taken
during transport and handling.
1.2 Features
n High accuracy and reliability
n Positive temperature coefficient;
fail-safe behavior
n Temperature range −40 °C to +300 °C
n Long-term stability
n Virtually linear characteristics
n Nickel plated leads

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.
