Through Hole Resistors are electrical components used for power dissipation in electrical circuits. FKN3WSJR-73-47R resistors are used for applications that do not require high current capability, instead relying on the power requirements of the circuit to dissipate heat. This type of resistor is especially useful in transformer circuits, where the power level of the circuit needs to be kept relatively low.

FKN3WSJR-73-47R resistors are used to limit the current in a circuit, and can be found in a variety of applications. The most common applications of these resistors are in power supply designs, for controlling the amount of current delivered to the circuit. In addition, these resistors are useful in motor control circuits, to regulate the current in order to increase the efficiency of the system. They are also commonly used in DC motor speed control systems, as they help regulate the speed of the motor.

The FKN3WSJR-73-47R resistors are available in both surface mount and through hole formats. The through hole resistor is typically the larger of the two, and is designed to be soldered directly to the circuit board. The resistor itself consists of a metal core, with resistive elements wrapped in an insulating sleeve. This type of resistor should be heated and soldered onto the circuit board, to ensure that the connection is secure. Once in place, the resistor will provide a resistance that will limit the amount of current delivered to the circuit.

The working principle of a FKN3WSJR-73-47R resistor is simple. When a current is passed through it, the resistance of the metal core generates heat and decreases the current passing through. The power dissipated in the resistor also increases as the amount of current decreases, until a point is reached where the power dissipated in the resistor is equal to the power supplied to the circuit. The resistor then acts as a current limiter, reducing the flow of current to the circuit while still allowing for the necessary power requirements.

The FKN3WSJR-73-47R resistors are typically used in applications where the power requirements of the circuit are low and the current requirements need to be kept under control. They are used in power supplies to limit the current delivered to the circuit, and in motor control circuits to regulate the speed of the motor. The resistors are also commonly found in DC motor speed control systems, as they help to regulate the speed of the motor.
