Through Hole Resistors

Through hole resistors are components that are wired into the board by going through a hole in the circuit. They are typically constructed of a resistive element, composed of a non-conductive material, and a lead wire that can provide a connection between two terminals or sets of points. The resistance of the resistor is usually determined by the number of turns of the lead wire. As a resistor, it serves to reduce the power/voltage input to the circuit, usually by diverting some of the current away from its load.

The 90J13 is a variable through hole resistors that is used in various applications, such as in adjustable level motors, stepper motors, light dimmers and so on. It is composed of resistive material around a hollow cylinder with a tapped end. The tapped end allows for various taps or adjustments that can be done to modify the resistance. A lead wire is connected to each end of the resistor, allowing connection to other points on the circuit board.

To adjust the resistance of the 90J13, the lead wire must be connected to the correct terminals. The resistance value is then determined by the number of turns and pitch of the wire. If the pitch is too tight, the wire may not be able to move and the resistance remain unchanged. On the other hand, if the pitch is too lax, the resistance can be too low.

The 90J13 through hole resistor is widely used in many modern applications. It is adjustable and can be used to change the working parameters of a circuit. For example, it can be used to change the fan speed or the voltage output of an electronic device. It can also be used in stereo systems to adjust the overall volume. Additionally, it can be used for regulating electric equipment, such as in the heating and cooling system of a home.

The working principle of the 90J13 through hole resistor is based on Ohm’s Law. According to Ohm’s Law, the voltage across the resistor is equal to the current multiplied by the resistance. When the number of turns and pitch of the wire are changed, the resistance of the resistor increases or decreases accordingly. This allows the user to adjust the circuit to their desired specifications.

The 90J13 through hole resistor is a versatile tool and can be used in many applications. It is easy to install and adjust, and is available in a wide range of resistances. It is also reliable and provides fairly consistent performance.
