3318P-1-104 Potentiometers, Variable Resistors

Trimmer Potentiometers

3318P-1-104 application field and working principle is a type of trimmer potentiometer. This type of potentiometer is a type of adjustable resistor used to electronically control the flow of current in circuits. It is most commonly used in applications where low power consumption, small size, and consistent performance are desired.

Trimmer potentiometers consist of a base, a tap conductor and a sliding contact. The base is a dielectric material, usually an insulator such as plastic, and is placed between two conductors, called the tap conductor and slider contact. The slider contact slides along the tap conductor and is used to adjust the current flow in the circuit. The slider contact and tap conductor are made of conductive materials such as copper, silver or aluminium.

The slider contact is connected to a shaft assembly, which allows for manual adjustment of the current flow. The shaft assembly is connected to a resistive element, usually a carbon-film, wire-wound or metal-film resistor, and is adjustable by twisting the shaft. The resistive element can be adjusted to vary the resistor\'s resistance. This allows it to be used to fine-tune the current flow in a circuit.

Trimmer potentiometers are used in a variety of electronic applications, such as controlling the current flow in an audio system, adjusting the frequency of a radio signal, or controlling the brightness of a light. They are also used in a variety of consumer electronics, including portable devices, digital cameras, and electronic scales.

Trimmer potentiometers offer several advantages over other types of adjustable resistors. They are small in size and offer consistent performance. They can be adjusted with greater precision than other types of resistors. They are also often used in applications where circuit board size is limited.

Trimmer potentiometers can be found in a variety of shapes and sizes. They are available in horizontal, vertical, right-angle and round configurations. The size of the trimmer potentiometer is determined by the circuit and application it is used in.
