Through Hole Resistors - FCR2WSJR-52-390K

Through hole resistors are widely used across a range of applications in the world of electronics and electrical engineering. These resistors are a fixed electrical component used for controlling the flow of electrical current and are often used to limit the current running through a circuit. The FCR2WSJR-52-390K is a type of through hole resistor, commonly found in electronic circuits. This article seeks to answer the questions: What is the working principle behind it? What are the most common application fields?

What is the Working Principle of a Through Hole Resistor?

At its core, the through hole resistor is designed to control the amount of current that flows through an electrical circuit that the resistor is connected to. The resistor does this by controlling the voltage across it, and the current through it. A resistor has a distinct electrical property known as resistance, which is commonly symbolized with the Greek letter rho (ρ). The resistance of a particular resistor is determined by the materials used to create it. The most commonly seen type of resistors use carbon as the main component. Carbon is mixed with other elements, such as copper, to customize the resistance of the resistor. In the case of the FCR2WSJR-52-390K, the resistor is composed of a thick film of this carbon-copper material, giving it its resistance of 390K.When mounted to a circuit board, the resistor is connected to two terminals. When a component connected on one side sends electricity to the other side, the electrical current must pass through the resistor, at predetermined levels determined by the resistance of the resistor.

Applications and Uses of Through Hole Resistors

Through hole resistors are used in almost all types of electronic devices, from phones to computers. Their most common use is the regulation of electricity in an electronic device. Carrying too much or too little current can be dangerous and cause short circuits and destruction of components. The resistor is used to ensure that the correct level of electrical current is always maintained. The FCR2WSJR-52-390K is commonly used due to its large resistance value and its ability to handle a high amount of power. This kind of resistor is usually used for power-related operations, such as the input or output of a device. For example, it can be used to limit the current going into a loudspeaker or to limit the power going to an amplifier.Other common applications for through hole resistors include the creation of audio tone control circuits, and as part of oscillator circuits used in a variety of devices.

Advantages of Through Hole Resistors

The primary advantage of through hole resistors is their ability to handle a higher amount of power than other types of resistor. The larger size of the FCR2WSJR-52-390K allows it to dissipate more heat, making it an ideal choice for applications that require a high amount of power. The other advantage of through hole resistors is their accuracy. The way in which the resistor is constructed means that it is possible to predict the resistance value very accurately. In addition, they are resistant to shock and vibration, making them ideal for use in automotive and industrial applications.

Conclusion

The FCR2WSJR-52-390K is a type of through hole resistor used in a wide range of applications. Its ability to handle high amounts of power makes it ideal for power-related operations. In addition, its accuracy and resistance to shock and vibration makes it ideal for use in industrial and automotive applications. Through understanding of the working principle, application fields, and advantages of this type of resistor, engineers can make an informed decision on what type of resistor to use for their particular project.
