Through hole resistors are resistors with leads attached at two end terminals. In such resistors, the resistor\'s body protrudes out of the circuit board, allowing a lead to be soldered to the circuit board. One of the most common through hole resistors is the MFR200DBE73-221R.

The MFR200DBE73-221R is an axial leaded resistor which is used in a variety of applications. This type of resistor is typically used in power supplies, motor controls, and audio applications. The overall design of this resistor is simple and straightforward, making it ideal for a wide range of applications.

The MFR200DBE73-221R is built with a resistor element and two metal caps. The resistance of the resistor element is determined by the material, length, and width of the element. The caps provide stability and protection to ensure that the resistance does not change in time. The caps are also important for dissipating heat, as all resistors generate heat and it is important to prevent thermal runaway.

The MFR200DBE73-221R is rated for a maximum power dissipation of 200W. The maximum voltage rating of this resistor is 250VAC. The tolerance rating of the resistor is 5%. The standard current rating of the resistor is 4A.

The MFR200DBE73-221R works on the principle of Ohm\'s Law. According to Ohm\'s Law, the current through a conductor is directly proportional to the voltage applied across the conductor, provided the temperature does not change. Therefore, when a voltage is applied across the resistor, the current is determined by the resistor value.

The MFR200DBE73-221R also follows the Power Law. According to the Power Law, the power dissipated in a resistor is directly proportional to the square of the voltage applied across the resistor. This means that when the voltage is increased, the power dissipation of the resistor increases exponentially.

In conclusion, the MFR200DBE73-221R is a very useful and reliable through hole resistor. This resistor is used in a wide range of applications and has a simple construction. It has a maximum power dissipation of 200W, a voltage rating of 250VAC, and a tolerance rating of 5%. It also follows the laws of Ohm\'s and Power, making it an ideal resistor for power electronics and audio applications.
