NTC Thermistors are devices used to measure temperature. These thermistors possess a temperature-dependent electrical resistance which can be used to measure the temperature of an object accurately. The KR103J0J NTC Thermistor is a surface mountable chip designed to offer reliable temperature sensing for applications such as medical devices and automotive electronics.

The KR103J0J can measure temperatures over a wide range from -55 degrees Celsius up to 150 degrees Celsius with an accuracy of 0.5 degrees Celsius. The small package of the KR103J0J also enables easy installation with minimum space requirement on PCBs for a variety of applications. It has a resistance of 10 kiloohm at 25 degrees Celsius and a B constant of 4500.

The working principle of the NTC thermistor is based on the physical phenomenon that the electrical resistance of materials changes with its temperature. The material used in the KR103J0J consists of manganese and nickel which has a negative temperature coefficient, meaning its resistance decreases with increased temperature. This change in resistance is small but measurable which helps the KR103J0J accurately sense the temperature of objects.

The construction of NTC thermistors can vary from many shapes and sizes depending on the application. The KR103J0J is a small surface-mountable chip which is usually mounted below the object whose temperature is being measured, for accurate results. The chip has two conductors, one of which is held at a constant temperature. The other conductor is connected to the object whose temperature is being measured and as its temperature changes, so does the resistance. This change in resistance is then monitored and the actual temperature of the object can be determined.

The KR103J0J NTC thermistor can be used in a variety of applications ranging from medical devices, automotive electronics, industrial automation and HVAC systems. It is a cost-effective and reliable solution for temperature sensing and can be used to accurately measure the temperature of objects. It is also widely used in refrigeration and air conditioning systems due to its high temperature range, accuracy and reliability.
