Through Hole Resistors

Through hole resistors are one of the most widely used electronic components for their simple structure, long service life and cost-effectiveness. FCR50SJT-52-12K is a kind of through hole resistors, which is found frequently in the industrial, automotive, and consumer electronic projects, such as voltage or current control related applications. In this article, we will discuss the application field and working principle of this kind of through hole resistor.

Application Field

FCR50SJT-52-12K is featured by its small and compact size, which makes it ideal for use in confined spaces. It can be applied in a variety of different projects, such as in the electrical current control circuits. Besides, this kind of through hole resistors can also be used to limit current flow in circuits or to act as safety fuse, which is often used in automotive and industrial projects. FCR50SJT-52-12K can work as a potentiometer, which is often used in adjustable voltage or current control projects. It also can be applied in DC motor control circuits, where these through hole resistors can serve as a variable resistor for motor speed control.

Working Principle

The working principle of a through hole resistor is quite simple. The resistor is composed of a conducting material (usually metal) encapsulated in a ceramic casing or in a plastic one. It consists of two conductive plates, the two terminals which allow current to flow through the resistor. In this type of resistor, the conducting material is in the form of thin layers of metal oxide, which can act as resistors.When electricity flows through the resistor, the electrons in the conducting material can be forced to move in different directions. As a result of this movement, a small electric current is formed and this current has some resistance to changes in voltage due to the fact that the metal oxide has limited conductivity. The resistance offered by the metal oxide affects the flow of current and therefore the voltage or current can be changed by varying the resistance of the resistor.

Conclusion

Through hole resistors, like FCR50SJT-52-12K, are popular electronic components for their simplicity, long-term stability, and cost-effectiveness. In this article, we discussed the application field and working principle of this type of through hole resistor. As discussed, it can be used in a variety of projects, such as DC motor control, voltage or current control, and safety fuse. Its working principle is based on the principles of electricity and the limited conductivity of the metal oxide.
