Through Hole Resistors

Through hole resistors are resistors that are installed in place through a hole in the circuit board. They are attached to the board using two or more leads that are connected to each other in series or parallel to create a resistant value. Through hole resistors are the most popular type of resistor used as they are easy to install, have a relatively low cost, and are able to exist in a wide variety of shapes and sizes.

FCB4220RJ Application Field and Working Principle

The FCB4220RJ through hole resistor is a cylindrical and axial leaded component that is typically used as a low-ohmic value for various power applications. These resistors are widely used in power supplies, automotive, and telecommunications due to their electrical resistance per unit length. Generally, their total resistance depends on the length of the cylindrical body.

The working principle of the FCB4220RJ through hole resistor is relatively simple. With an electrical voltage applied to the ends of the resistor, an electric current is drawn into the resistor. This current passes through the wire and resists the flow of the current, thereby dissipating the energy in the form of heat. This can becalculated using Ohm’s law, which states that the current in the resistor is equal to the voltage applied across it divided by the resistance of the resistor.

As the resistance of the resistor is inversely proportionally to the length of the body, increasing the length of the body will result in a decrease of the resistance of the resistor. This is typically achieved by adding a second or greater resistance value to make up the total resistance value.

The FCB4220RJ through hole resistor has the advantage of being easy to install and replace. They are also inexpensive compared to other resistors, as they are typically much smaller in size and less complex in comparison, thereby reducing expenses associated with manufacturing. Additionally, they are available in a vast range of resistance values, making them suitable for a variety of applications.

Overall, the FCB4220RJ through hole resistor is an effective and economical resistor with high accuracy, suitable for a wide variety of power applications. It has the advantages of being easy to install, having a low cost and a wide range of resistance options.
