KTY81 series Silicon temperature sensors Rev. 05 — 25 April 2008 Product data sheet 1. Product profile CAUTION 1.1 General description The temperature sensors in the KTY81 series have a positive temperature coefficient of resistance and are suitable for use in measurement and control systems. The sensors are encapsulated in the SOD70 2 in-line leads plastic package. Other special selections are available on request. This device is sensitive to ElectroStatic Discharge (ESD). Therefore care should be taken during transport and handling. 1.2 Features I High accuracy and reliability I Positive temperature coefficient; fail-safe behavior I Long-term stability I Virtually linear characteristics 1.3 Quick reference data Table 1.

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.
