Through Hole Resistors, such as MFR100FTF73-1K07, is an important component in electronic industry, and widely used for the purpose of current and voltage limiting, capacitance dividing, power factor correction, temperature calibration, frequency division, game audio equipment and other fields. The application fields and working principle of MFR100FTF73-1K07 will be discussed in this paper.

MFR100FTF73-1K07 is a through coating resistor, which is formed with the epoxy resin coating. It is composed of metal and nonmetal resistors. The metal resistor is made of different metal materials, such as aluminum, copper, and nickel. The nonmetal resistor is dielectric material, such as glass, plastic, porcelain, ceramic, and other materials. The resistance of these different materials is different.

MFR100FTF73-1K07 is a kind of high voltage, high accuracy, low power dissipation, and excellent stability. It is widely used in electric power, telecommunication industry, industrial automation control, and other industries. It can effectively limit the power factor of the transmission line, as well as improve the voltage regulation and frequency stability. The application fields of MFR100FTF73-1K07 include:

1) Voltage regulation and frequency stabilization in electricity industry: The resistor can effectively control the voltage by controlling the current flowing through the transmission line, thus improving the electrical performance of the system.

2) Transformer protection in telecommunication industry: It can be used to protect the transformer in telecommunication industry from over-voltage and over-current.

3) Relay protection in industrial automation control: The resistor can be applied to protect the relay in industrial automation control from over-voltage and over-current.

The working principle of MFR100FTF73-1K07 is based on the relationship between electrical resistance and temperature. The resistance of the MFR100FTF73-1K07 is affected by temperature changes, which is known as "thermal sensitivity". The resistor\'s temperature coefficient of resistance indicate the resistance change of the resistor when the temperature is changed. This coefficient is usually represented as the temperature coefficient (TCR) in the unit of ohms per degree Celsius (Ω/°C).

In addition, the resistor is also known as a self-heating resistor. It is because when the current flows through the resistor, the heat generated by the current will increase the temperature of the resistor, and consequently changing its resistance. This phenomenon is known as thermal runaway, and it will cause the resistor to become unstable. in this way, the resistor will need protection, such as adding the appropriate over-temperature protection devices.

In conclusion, MFR100FTF73-1K07 is a through hole resistor with a broad range of application fields. Its working principle is based on the relationship between electrical resistance and temperature. It is widely used in electricity, telecommunication industry, industrial automation control, and other industries. Its temperature coefficient of resistance and enough heat dissipating ability make it capable of providing excellent performance. Therefore, MFR100FTF73-1K07 is an important component in electronic industry.
