Through Hole Resistors

The RN55D7501FB14 application field and working principle is typical of through hole resistors. Though-hole resistors are electronic components used to limit current flow and reduce voltage in a circuit. Through-hole resistors are the oldest type of resistors, and are used in lights, motors, and various other applications. They come in a variety of shapes and sizes, but all operate on the same basic principle.

Application Field

Through-hole resistors are usually mounted on a Printed Circuit Board (PCB) and then soldered into the circuit. They are commonly used for controlling the current and voltage in sensitive circuits. One example is the protection of a device\'s write cycles, in which the regulator must precisely control current flow and voltage. Through-hole resistors are also used for audio applications, such as to control the amplitude of audio signals.

Advantages

Through-hole resistors are advantageous for a few reasons. Firstly, they can be used at higher temperatures and have higher wattage ratings than surface mount resistors. Secondly, they are generally easier to mount and solder than surface mount resistors, since the large surface area facilitates the joining of components. Finally, some applications require resistors to physically bind to the board, such as through-hole current-sensing Resistors.

Installation

Installing a through-hole resistor is a fairly straightforward process. First, tin the through hole of the board with a thin layer of solder. Next, apply a small amount of flux to the solder. Then place the component into the through hole and use a soldering iron to make a connection between the component and the board. Finally, use some pliers to hold the resistor in place and a soldering iron to make contact and join it to the board.

Working Principle

The basic working principle of a through hole resistor is based on Ohm\'s law. This law states that current in a circuit is directly proportional to the voltage across its terminals. This is a linear relationship, so the current is equal to the resistance multiplied by the voltage. The resistance is the key factor in through hole resistors. The resistance of the resistor can be controlled by altering its physical structure, such as the shape and size of the core, or by adding or removing conductive material. By altering the resistance, the resistor can be used to limit, control, or reduce the current or voltage in a circuit.
