Temperature sensors are important instruments used in various industrial, commercial, and consumer applications to measure temperature in the environment or in a system. NTC thermistors are one type of temperature sensor that use the NTC (Negative Temperature Coefficient) thermistor property as the sensing element. The MA100BF103CN is a precision surface mount NTC thermistor used for temperature measurements in a wide variety of applications. This article will explain the application field and working principle of the MA100BF103CN.

The MA100BF103CN is a precision NTC thermistor package consisting of a ceramic body with small taped wires for connecting to the reading instrument. The ceramic body is filled with a proprietary mixture of nickel oxide and manganese dioxide, which act as the sensing element in the thermistor. This mixture is specifically formulated to have a large negative temperature coefficient (NTC) curve that provides exceptional accuracy over a wide range of temperatures. The sensing element is waterproof, making it an excellent choice for measurements in damp or wet environments.

The MA100BF103CN is ideal for use in medical, environmental, and industrial applications where precise temperature measurement is critical. It is typically used in heaters, air conditioners, ovens, and other appliances where temperature monitoring and control is necessary. It can also be used in devices that measure temperature in order to adjust the device’s performance such as in hot water tanks, air purifiers, and freezers. The MA100BF103CN is also used to control industrial processes such as in stamping, welding, hot forging, and extrusion.

The working principle of the MA100BF103CN is based on the NTC thermistor property. An NTC thermistor is a temperature-sensing element with a resistance that decreases as temperature increases. When the temperature of the thermistor increases, its resistance decreases. This decrease in resistance is based on the formulae:

R = R0 * e^(-B * (1/T-1/T0)

where R0 is the resistance at a reference temperature, T is the temperature of the thermistor, and T0 is the reference temperature. B is the thermistor’s beta or NTC coefficient.

The resistance of the MA100BF103CN can be measured using a circuit with a voltage source and two resistors. When a voltage is applied to the circuit, a current will flow through the thermistor. As the temperature of the thermistor changes, its resistance will also change. This change in resistance will cause a change in the current flowing through the thermistor. The change in current can then be measured and used to calculate the temperature of the thermistor.

In summary, the MA100BF103CN is a precision surface mount NTC thermistor used for temperature measurements in a wide variety of applications. It is ideal for use in medical, environmental, and industrial applications where precise temperature measurement is critical. The working principle of the MA100BF103CN is based on the NTC thermistor property where its resistance decreases when the temperature increases. The resistance of the MA100BF103CN can be measured using a circuit with a voltage source and two resistors. And by measuring the change in current, the temperature of the thermistor can be calculated.
