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.

R−55/R25	resistance ratio	Tamb = −55 °C and 25 °C	0.49	0.50	0.51
τ	thermal time constant; note 1	in still air	−	20	−	s

	rated temperature range		−55	−	+175	°C

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.
