KW103J2 is an NTC thermistor, which stands for Negative Temperature Coefficient thermistors. It is a type of temperature sensor that operates on the principle of varying resistance with temperature. It is a well-known and widely used device and is utilized in numerous application fields. In this article, we will explore the KW103J2 application field and working principle.

KW103J2 Application Field

The KW103J2 thermistor is a high-temperature thermistor characterized by improved reliability and accuracy. It is suitable for use in a wide range of temperature detection applications, such as automotive applications, consumer electronics equipment, industrial temperature measurement, thermocouple replacements, and HVAC systems. The device is also used for interfacing with microcontroller-based systems where accuracy and reliability are critical.

This thermistor is designed for high accuracy over a wide range of temperatures and is used for medical equipment, refrigeration/freezing equipment, temperature controllers, ovens, and microwaves among other applications. It is also suitable for high-temperature applications such as solar cells, indoor and outdoor environmental control, and industrial monitoring. The robust design of this thermistor ensures it is suitable for long-term and harsh environment applications.

KW103J2 Working Principle

The working principle of the KW103J2 thermistor is based on the principle of varying resistance with temperature. As the temperature increases, the thermistor\'s resistance decreases and vice versa. This is known as the negative temperature coefficient (NTC) characteristic. As a result, when the temperature of the thermistor increases, the voltage across it drops, thus allowing for accurate temperature measurements.

The thermistor\'s resistance changes are exponential in nature. This means that the resistance of the thermistor is proportional to the negative logarithmic of the temperature. This makes it possible to accurately measure temperature within an accuracy range of ±1.5°C for the KW103J2 thermistor over a range of -30°C to +200°C.

NTC thermistors are typically made from a combination of ceramic materials and metal oxides such as manganese, copper, cobalt, nickel, and zinc. Most NTC thermistors have a resistance of 10KΩ at 25°C. It is important to note that the NTC thermistor\'s resistance value must be determined for each temperature value.

In summary, the KW103J2 thermistor is an NTC thermistor, characterized by improved reliability and accuracy. It is used in a wide range of temperature detection applications and is suitable for use in long-term and harsh environment applications. The thermistor\'s resistance changes exponentially with temperature, making it possible to accurately measure temperature with an accuracy range of ±1.5°C for the KW103J2 over a range of -30°C to +200°C.
