The KTY83-1 series of silicon temperature sensors 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. Tolerances of 0.5% or other special selections are available on request.
The KTY83-1 series are silicon temperature sensors with a positive temperature coefficient of resistance. They are supplied in an SOD68 (DO‑34) package and are available with tolerances of 0.5% or special selections on request.
The data sheet lists detailed electrical characteristics such as resistance values at 25 °C, temperature coefficients, rated temperature range (‑55 °C to +175 °C), recommended operating current (1 mA for temperatures above 100 °C), and thermal time constants. Several tables give ambient‑temperature versus resistance data for each part number in the series.

| Temperature coefficient (TC) | -0.76 %/K |
| Rated temperature range | -55 °C to +175 °C |
| Ambient operating temperature | -55 °C to +175 °C |
| Continuous sensor current (typical) | 1 mA (up to 10 mA at 25 °C, 2 mA at 175 °C) |
