Trimmer Potentiometers are widely used to make adjustments on a circuit, allowing the user to vary the resistance in order to change the voltage or current of the circuit. The 3303C-1-202E is a small trimmer potentiometer, suitable for a wide range of applications where a small, low-power adjustment is needed. The most common uses are for adjusting gain, sensitivity and bias in audio signals.

The 3303C-1-202E has a shaft movement range of 20 degrees and can handle up to 0.1 amps of power at a maximum voltage of 18V. It is an adjustable type trimmer, which means it can be adjusted by turning the adjusting screw, controlling resistance have a range from 0 to 10Kohms. The 3303C-1-202E is also available with both top and side adjusters with various washer types, making it suitable for a range of applications.

The 3303C-1-202E is typically used in circuits where the tolerance of the component is not critical and adjustments may have to be made periodically. It works by intercepting and limiting the current running through a circuit, allowing it to be adjusted to the desired strength. The 3303C-1-202E is a three terminal device, meaning it can be used as a variable resistor or as a variable voltage divider.

In variable resistor applications, the two outer terminals are connected to the source of the circuit, while the middle terminal is connected to the load. The resistance between the two outer terminals can be adjusted by turning the screw located on the middle terminal, allowing the user to limit the current going through the circuit. This thus allows for the adjustment of the circuit parameters, such as gain, tone, sensitivity and bias.

In variable voltage divider applications, the two outer terminals are again connected to the source, while the middle terminal is connected to the load. This time the resistance between the two outer terminals is adjusted by changing the voltage on the middle terminal. This allows the user to change the voltage on the load, while the current remains constant.

The 3303C-1-202E is ideal for applications requiring small adjustments such as gain, audio tones, sensitivity and bias in audio signals, and is also suitable for controlling motors and other analog devices. The device can be mounted using standard metric threads, and is also available with many washers to suit different applications. It is relatively low-cost and easy to use, making it suitable for both hobbyists and professionals alike.
