Through Hole Resistors are widely used industrial components in various sectors due to their attractive features such as power ratings, voltage ratings, high quality and reliability. The MFR200FBF73-120K is a through hole resistor that provides a high power rating and voltage rating, making it a suitable choice for a wide range of applications. In this article, we will discuss the application field and working principle of the MFR200FBF73-120K.

Application Field

The MFR200FBF73-120K is a through hole resistor providing a power rating of 200 Watts and a voltage rating of 200 Volts. This makes it ideal for use in a variety of applications, ranging from industrial to automotive. In the industrial field, this resistor can be used in switching power supplies, electric motor control circuits, servo drive systems, solid-state relays, HVAC systems, and many more. In the automotive sector, it can be used for circuits powering airbags, digital dashboards, ABS, and other safety-critical functions. Also, it is suitable for use in consumer products like LED lights and radios.

Working Principle

The working principle of the MFR200FBF73-120K through hole resistor is based on the principle of Ohm’s law which states that the current passing through a conductor is directly proportional to the applied voltage. The resistance of the resistor is determined by the material of the resistor, where more resistance corresponds to a thicker conductor material. When an AC voltage is applied across the resistor, current will flow through the resistor, producing heat. The resistor will then dissipate this heat, which is known as resistive power loss.

The amount of resistance provided by the resistor can also be adjusted by changing the length of the resistor. Longer resistors provide greater resistance while a shorter resistor provides a lower resistance. This makes it possible to alter the current flowing through the resistor by changing the length of the resistor. It is also possible to alter the resistance of the resistor by changing the material of the resistor.

The MFR200FBF73-120K also has a temperature coefficient of resistance, which indicates the rate at which the resistance of the resistor varies when exposed to changes in temperature. This allows the resistor to maintain a consistent resistance despite changes in temperature.

Apart from providing resistance, the MFR200FBF73-120K also provides protection to the circuits it is connected to. It mitigates spikes in the current and voltage, which could otherwise cause permanent damage to the circuit components.

In conclusion, the MFR200FBF73-120K through hole resistor is a versatile industrial component that can be used in a wide range of applications due to its high power rating and voltage rating. It works on the principle of Ohm’s law and can provide protection to the connected circuits by mitigating spikes in current and voltage. Thus, it is an ideal choice for industrial and automotive applications.
