Through Hole Resistors

Through Hole Resistors are widely used in many applications and their working principles are relatively simple. In this article, we will explore the application field and working principle of the 20J4K5E Resistor.

Applications

Through Hole Resistors are used in a variety of applications, including power supplies, inverters, amplifiers, digital circuits, and oscillators. They are also often used in power switching circuits, converter circuits, and signal transmission circuits. In addition, resistors can be used to limit current, divide voltage, or adjust circuit timing and speed.

The 20J4K5E Resistor is especially well-suited for the applications mentioned above due to its ability to withstand high temperatures and power ratings. It is also used in circuit boards, contactors, variable speed drives, motor protection, and soft starters.

Working Principle

The working principle of Through Hole Resistors is relatively straightforward. Resistor materials usually have a high resistance value which prevents the flow of electric current. This resistance can be adjusted by changing the size and shape of the resistor, or by selecting different materials.

The 20J4K5E Resistor is an example of a fixed Through Hole Resistor, meaning that its resistance is not adjustable. This resistor is constructed from a carbon composition material and has a 4-inch diameter. Its resistance is rated at 0.5 Ohms and its wattage rating is 20W.

The 20J4K5E Resistor is very efficient and reliable due to its high resistance value which can withstand temperatures up to 350°C. This makes it ideal for applications that require high temperatures or power ratings.

Conclusion

Through Hole Resistors, such as the 20J4K5E Resistor, are widely used in a variety of applications. Their working principles are relatively simple and involve changing the size and shape of the resistors, or selecting different materials, in order to adjust the resistance value. The 20J4K5E Resistor is an example of a fixed Through Hole Resistor and is well-suited for applications that require high temperatures or power ratings.
