NXP Thermistor

The KTY series of silicon PTC thermistors from NXP Semiconductors are ideal for use as temperature sensing devices in measurement and control systems. Whilst non-linear, they exhibit highly repeatable, predictable and stable resistance versus temperature characteristics. The KTY sensors have a wide operating range and long operating life and are available in various package styles and initial tolerances.

Fail-safe positive temperature coefficient
Semi-logarithmic R/T characteristic
Close resistance tolerance (KTY81/110 = ±1%)

Thermistors - PTC (Positive Temperature Coefficient)

Positive temperature coefficient Thermistor is designed for general purpose over-current, over-voltage, and direct over temperature protection. Applications in TV tube degaussing, choke and transformer protection, time delay, motor starting, liquid level sensors and overflow protection for oil tanks.
