Through Hole Resistors are resistors which have two metal leads protruding from either end. These leads are then inserted into the multi-aperture in a circuit board (PCB). The leads span two opposite sides of the PCB, forming a conductor and a resistor component joined together. These type of resistors are used to create the necessary current flow within a circuit.MFR100FRF73-475K is a type of Through Hole Resistor. It is a variable resistor with five terminals that can be adjusted to different resistance values. This resistor is used in a range of applications including in audio equipment and general purpose monitoring. It features an adjustable feature which makes it a great choice for applications that require several variables in electrical resistance.The working principle of MFR100FRF73-475K is based on Ohm\'s Law. This states, "the current passing through a conductor is proportional to the potential difference (voltage) across it." In other words, the current flowing between two points in a circuit is proportional to the voltage across them. When a resistor is in series with a circuit, the current that will pass through it is determined by the voltage across it and the resistance of the resistor. Therefore, when a MFR100FRF73-475K resistor is inserted into a circuit, the variable terminals can be adjusted to a desired resistance value to control the amount of current that passes through it.MFR100FRF73-475K comes in three different power rating categories which are 0.25 watts, 0.5 watts and 1 watt. These ratings are based on the degree of power dissipation which occurs in the resistor. These power ratings allow for different applications. For example, a 0.25 watt rating is suitable for low power usage such as with audio equipment while the higher wattage ratings are suitable for applications requiring higher power, such as in automotive or industrial equipment.In addition to the power rating, MFR100FRF73-475K comes with four different tolerance ratings. These ratings indicate the degree of accuracy of the resistors. These range from 10%, 5%, 2.5%, and 1%. The tolerance rating is important when exact resistance values are needed.MFR100FRF73-475K also features a temperature coefficient which affects the resistance. A temperature coefficient is a measure of the change in resistance relative to the change in temperature. This feature allows the user to maintain the accuracy and performance of the resistor over a wide range of temperatures.Overall, MFR100FRF73-475K is a versatile resistor which is suitable for a range of applications. Its adjustable feature combined with its power, tolerance and temperature coefficient ratings make it an ideal choice for use in a variety of electrical applications.
