Through Hole Resistors

A through hole resistor, such as the NKN500JR-91-8R2, is a passive device consisting of a resistive element enclosed in an insulating medium. It is designed to reduce the electric current flowing through a circuit in order to prevent excessive flow or to provide a voltage drop for applications such as controlling current flow, limiting current over short time periods, or defining a specific voltage level. They are available as a single component or as a part of an assembly. An example of assembly would be a switchable resistor. Through hole resistors find a wide range of applications.

Application Field

Through hole resistors have a wide range of applications. In the transportation industry, through hole resistors are often used as an adjustable load for generator arms or as neutralizing devices in high voltage systems. In communications applications, they are used to control the flow of current in high voltage circuits, as well as to limit current over very short time periods. Other common applications include power supplies, signal processing, and audio systems. In general, through hole resistors are a fundamental component of many electronic circuits.

Working Principle

Through hole resistors work by using an electrically resistive element to oppose current flow. The resistance to electron flow is determined by the materials used to manufacture the resistor, as well as the dimensions of the component. Every material has a specific electrical resistance. When a through hole resistor is placed in a circuit, the electrons that are flowing from the power source toward the load must pass through the resistor. The resistor will oppose the electron flow, thus creating a voltage drop and slowing the overall flow of current through the circuit.

The electrical resistance of a through hole resistor can be adjusted by altering the dimensions of the component. This is accomplished by manipulating its internal components, such as its length, width, and thickness. By accurately measuring the internal components, the electric resistance of the resistor can be precisely determined. The internal components also influence the maximum voltage and power the resistor can tolerate before it fails.

Conclusion

Through hole resistors, such as the NKN500JR-91-8R2, are an essential part of many electronic circuits. By utilizing the electrical resistance of materials, they work to oppose current flow and reduce the electric current flowing through a circuit. Through hole resistors are widely used in transportation, communications, power supplies, signal processing, and audio systems, and their performance can be adjusted by manipulating the internal components.
