PTC thermistors are temperature sensors whose electrical resistance varies as a function of temperature. As temperature rises, the resistance increases for most types. This distinct property of PTC thermistors makes them well suited for over-current protection devices, and they are commonly used in many electronic products.

The KTY11-7 is a multipurpose PTC thermistor which is suitable for a wide variety of application fields. It has a fast response time and is cost effective. The KTY11-7 PTC thermistor exhibits highly stable properties over a wide temperate range and is able to maintain consistent performance for prolonged periods of operation.

The KTY11-7 operates on the principle that the electrical resistance of a material is dependent on the temperature of the environment. The material’s resistance to current increases with the temperature of the environment, which makes the thermistor an effective sensing and over-current protection device. This allows the KTY11-7 PTC thermistor to be used as an accurate temperature sensor as well as an over-current protection device.

In temperature sensing applications, the KTY11-7 PTC thermistor is typically used as part of a closed loop system. The thermistor is connected to a voltage source and measures the change in resistance as the temperature of the environment changes. The voltage source then adjusts its output voltage to keep the measured resistance consistent with the pre-set value. This system closes the loop, which is constantly measuring the environment temperature and automatically adjusting the electrical parameters of the system.

In over-current protection applications, the KTY11-7 PTC thermistor is used to detect the rising current in an electronic circuit. When the current exceeds the pre-set value, the temperature of the thermistor starts to increase. The increased temperature causes an increase in the electrical resistance of the thermistor, which limits the current flow. This allows the thermistor to act as a current limiter, protecting the circuit from excessive current.

In summary, the KTY11-7 PTC thermistor is a multipurpose thermistor that is suitable for numerous application fields. Its fast response, consistent performance and stability over a wide temperature range make it an excellent choice for temperature sensing and over-current protection applications.
