KT103J2 Temperature Sensors - NTC Thermistors

NTC thermistors, or Negative Temperature Coefficient thermistors, are highly sensitive electronic components capable of accurately measuring temperature changes in a wide range of applications. The KT103J2 NTC thermistor is a highly accurate temperature sensing device designed for high temperature applications. It is an ideal choice for precision temperature control in a variety of industrial and consumer products.

Application Field

The KT103J2 NTC thermistor is typically used in applications that require accurate temperature control over a wide temperature range. It is particularly suitable for applications in ovens, industrial furnaces, and other high temperature applications. It is also used in a variety of other products, including autopilot temperature control systems, automotive exhaust systems, and high-tech refrigeration systems. This thermistor can also be used as a replacement for thermocouples in some applications due to its accurate temperature sensing capabilities.

Working Principle

The KT103J2 NTC thermistor is a two-terminal device that works on the principle of heat-induced resistance change. It consists of a metal oxide ceramic material which has been man made to respond to temperature fluctuations in a predictable manner. This material changes its electrical resistivity as the temperature changes. The great advantage of the KT103J2 is its wide operating temperature range, which ranges from -40°C to + 200°C. As the temperature rises, the electrical resistance of the material decreases.

The KT103J2 NTC thermistor is more accurate than traditional thermistors due to its temperature-dependent behavior, which is defined by its temperature coefficient of resistivity (TCR). The TCR is the ratio of resistance change to temperature change. The KT103J2 NTC thermistor has a TCR of -4800, which means that for every 1°C change in temperature, the resistance changes by -4800 ohms. This high accuracy makes it one of the most popular thermistors for precision control applications.

The KT103J2 NTC thermistor is highly durable and reliable, even in extreme temperatures and environments. It has excellent accuracy and repeatability, making it suitable for long-term temperature monitoring applications. This thermistor can be combined with a variety of electronic components to create temperature sensing systems, such as temperature monitors and controllers.

Conclusion

The KT103J2 NTC thermistor is an extremely accurate and reliable temperature sensing device. It is typically used in applications that require highly accurate temperature control over a wide range. It has excellent accuracy and repeatability, making it suitable for long-term temperature monitoring applications. It can be combined with a variety of electronic components to create temperature sensing systems.
