3296P-1-470LF

Trimmer Potentiometers

A trimmer potentiometer is an electronic component that controls voltage or current by varying the resistance of a potentiometer. The 3296P-1-470LF is a multi-turn trimmer potentiometer, with a total range of 470 ohms consisting of 20% increments. It has a maximum resistance value of 470 ohms at 10 turns of its rotary knob at its minimum position.

Application Field

The 3296P-1-470LF is a multi-turn, precision trimmer potentiometer, designed for a variety of industrial applications. This trimmer is suitable for adjusting voltage levels, providing an adjustable resistance in a wide range of applications. A common example of its application would be to adjust the resistance of a circuit in order to attain the desired voltage output. This potentiometer is also used in audio equipment to adjust volume down to very low levels. Additionally, it is often used in the field of telecommunications and medical equipment as well.

Working Principle

The 3296P-1-470LF trimmer potentiometer operates on a basic principle of varying resistance. It is essentially a three-terminal resistor with a sliding contact, referred to as the wiper, that runs along a resistance track. When the knob is adjusted, the wiper slides and touches the resistance track, creating a connection with the track. This creates a voltage at the output dependent on the resistance of that track at that point. The greater the resistance is on the track, the lower the voltage is at the output terminal. As the wiper makes contact with the track, its resistance decreases, increasing the voltage at the output terminal.

The 3296P-1-470LF has precisely calibrated tracks, with 20% increments of 470 ohms. As the knob is turned, the wiper slides along the track, creating a sliding connection between the wiper and track. This connection then varies the resistance value of the resistor, thereby changing the output voltage. Furthermore, this trimmer potentiometer is designed with stability and small size in mind, making it ideal for use in industrial applications or any other device where space is limited.
