PTC thermistors are temperature sensitive resistors with their resistances increasing with temperature. KTY23-7 is one of the most common thermistor families used for temperature sensing applications. Typical operating temperatures for this thermistor range from 0°C to 90°C and the resistance variation with temperature follows the Steinhart-Hart equation. The constant of the thermistor allows us to interpret the relationship between resistance and temperature.

KTY23-7 thermistors have a variety of temperature-sensitive applications that include temperature modulation and compensation in electronic circuits, temperature measurement in power supplies, and surge-protection current limits in circuit breakers. The device is also used in the manufacture of automotive components such as fuel pumps, air conditioning systems, and control systems. This thermistor is also used in medical devices, home appliances, and other consumer electronics.

Inertial navigation systems also employ KTY23-7 thermistors to detect changes in temperature. The thermistor\'s high sensitivity allows the navigation system to quickly and accurately detect changes in temperature and adjust its navigational calculations accordingly. This is useful in applications such as autonomous vehicles, where accuracy is paramount.

The working principle of KTY23-7 thermistors is based on its ability to convert heat energy into electrical energy. The heat energy can be generated from its own resistance or from the environment. When the thermistor is placed in an environment with a certain temperature, electricity flows through its lead wires, creating a heat flow from the circuit or from the environment to the junction of the thermistor. This heat energy causes the thermistor\'s resistance to vary and, in turn, produces a voltage difference between the leads. This voltage difference is then used to measure the temperature.

KTY23-7 thermistors are typically constructed from ceramic materials that are highly sensitive to temperature and are encapsulated in a protective epoxy coating to protect it from environmental elements. The device is usually connected to a printed circuit board or integrated circuit for temperature measurement and control. KTY23-7 thermistors are extremely reliable and accurate temperature-sensing components that can function in a wide range of environments and applications.
