Through Hole Resistors are electrical components that are designed to control the flow of an electrical current. They are commonly used in electrical circuits to provide an adjustable resistance in the circuit, allowing the user to adjust the flow of the current and thereby regulate the output of the device. The B20J125E Through Hole Resistor, also known as the Variable Resistor, is commonly used in applications where a variable resistance is required.

The B20J125E Through Hole Resistor is designed with a body that is 12.5 mm in diameter and has a height of 6.5 mm. The external construction of the resistor is generally made of nickel or a similar metal to ensure minimal heat conduction. The internal construction includes two electrodes, arranged such that both ends protrude out of the resistor body and are soldered into an appropriate circuit. One end is wired to the positive potential line of the circuit, and the other end is wired to the negative potential line. The resistance of the resistor is then adjusted by rotating the body, which allows the two electrodes to change their distance, thereby altering the overall resistance of the resistor.

The B20J125E Through Hole Resistor is especially useful in applications where the user needs to adjust the resistance of the electrical circuit. This is particularly said when a variable voltage or current is required. In addition, the device’s small size makes it ideal for use in portable electronic devices. Such devices include cell phones, digital cameras, and portable computers. Additionally, the device is often used in automotive applications, such as in fans, alternators, generators, and starters, in order to reduce the amount of current flow and thus save energy.

In summary, the B20J125E Through Hole Resistor is an effective component used in electrical circuits to regulate the flow of current. It is especially useful in applications where a variable voltage or current is required, as well as in portable electronics and automotive applications. The device is relatively small in size and has two electrodes that are arranged such that both ends protrude out of the body. By adjusting the distance between these two electrodes, the user is able to control the amount of current flowing through the resistor.
