3339P-1-474LF

Trimmer Potentiometers

Trimmer Potentiometers are consisting of three pins and used to adjust the current applied to a circuit, offering a variable resistance ranging from of 0 to 10,000 ohms.

3339P-1-474LF is a type of trimmer potentiometer with a 3/8" square shaft for adjustment. It provides a resistance range of 0 to 10,000 ohms and works with a rated current of 10mA and 25V of rated power. It’s also equipped with its own knob for easy and precise manual adjustment.

Application Field: 3339P-1-474LF is mainly used to fine-tune and adjust the electrical current in a circuit, such as for audio, radio, or TV, and can be used for volume, brightness, and other purposes. It’s also used in amplifiers and in instruments that measure electrical signals.

Working Principle:3339P-1-474LF functions by the user adjusting the knob connected to a two-terminal device, which acts like a resistor. When the knob is rotated, the resistance of the device changes accordingly. Small currents pass through the device, and these are applied to the circuit connected to it.

When the knob is rotated clockwise, resistance increases and current decreases, so the desired effect is achieved. Conversely, when turning it counterclockwise, resistance decreases and current increases. By operating the knob, one can adjust the current applied to the circuit correctly.

Trimmer Potentiometers, such as 3339P-1-474LF, are an integral part of any circuit, and its precise control over the applied current is fundamental for the circuit’s correct operation.
