Through Hole Resistors are common in many electrical and automated installations, and the type FKN2WSFR-73-3R is no exception. This type of resistor is categorized as a through hole resistor due to its construction, and is very useful in applications where high levels of current or voltage need to be managed.

The FKN2WSFR-73-3R type of resistor consists of a case made from a conductive material like aluminum or nickel, and then a ceramic core or resistor stack made up of two or more non-conductive materials. The casing is then filled with an insulating material such as a polyester or glass-fiber which provides an electrical insulation between the components. The resistor stack itself is made up of layers of different metals that maintain a constant level of resistance when connected to a circuit. The number of layers to be used depends on the desired resistance. For example, if a resistor needs a resistance of 5 ohms, then five layers of copper and five layers of aluminum, are required.

Depending on the application, the FKN2WSFR-73-3R can be used to either reduce the flow of electricity in an electrical circuit or limit current levels. In the former, they act as a choke because the resistance of the resistor stack limits the flow of electrons across it. By properly controlling the voltage and current, these resistors can help reduce the risk of overloading and damaging an electronic component. In the latter case, the resistor stack limits the current from an external source to the permissible electric current level tolerated by the circuit. This is done through a feedback system in which the current flowing through the resistor is monitored and adjusted as necessary.

These resistors are also commonly used in applications where precision of current or voltage is required. This means that they can be used to maintain a predetermined current by monitoring the resistance or the voltage across the resistor. This is beneficial in situations where there needs to be an exact amount of current or voltage supplied to the circuit at any given time.

Because the resistor stack is not directly soldered onto the circuit board, they are relatively easy to replace or repair. The individual layers of the resistor stack can be easily attached to the circuit board and then the electrical connections of the resistor checked. These resistors can also be stacked on top of each other to increase the overall resistance. This is useful when additional resistance is needed, such as in high current applications.

Overall, the FKN2WSFR-73-3R type of resistor is extremely useful in a variety of applications and provides a very helpful way to manage the flow of electricity and current. The use of these resistors can help protect sensitive electronic components from excessive current or voltage, and the individual layers of the resistor stack can be easily replaced or added as necessary.
