Trimmer Potentiometers and the 3290P-1-200

Potentiometers, also known as variable resistors or trimmer potentiometers, are components used in many electronic circuits. A potentiometer is an adjustable voltage divider which can be used to supply an adjustable voltage, used for setting gain in amplifiers, controlling output voltage in switching power supplies, and adjusting the frequency in timing circuits. Trimmer potentiometers are often used in precision circuits, where a precise setting is required.

The 3290P-1-200 is a trimmer potentiometer made by Bourns Inc, a leading manufacturer of electronic components. It is a miniature, surface mount rotary trimmer potentiometer used in a variety of circuit designs. It is available in 3 terminal, 2 terminal, and 3-position screwdriver versions.

The 3290P-1-200 is a low-cost, miniature trimmer potentiometer with 50Ω - 15kΩ resistance range and a maximum power rating of 0.05W. It has an operation temperature range of -55°C to +125°C. It is available in a variety of package styles such as surface mount, through-hole, and DIP (dual in-line package). It can be used in a wide variety of circuits such as operational amplifiers, switching power supplies, mobile audio amplifiers, and more.

Application Field

The 3290P-1-200 trimmer potentiometer is widely used for its flexibility and precision control. It is used in a variety of applications, including:

• Amplifiers – to adjust gain, volume, tone, and other parameters.
• Instrumentation – to adjust frequency, speed, sensitivity, and other parameters.
• Switching power supplies – to adjust the output voltage.
• Communication systems – to adjust frequency, gain, and other parameters.
• Sensor components – to adjust the sensitivity.
• Computer peripherals – to adjust the speed.
• Timing circuits – to adjust the timing.

Working Principle

The 3290P-1-200 trimmer potentiometer is a three-terminal device that consists of a resistive element, a wiper contact, and a third terminal for external connections. When the wiper contact is moved along the length of the resistive element, it changes the resistance between the two end terminals. This change in resistance can be used in a number of circuits to control the output.

For example, in an amplifier circuit, the 3290P-1-200 can be used to adjust the gain of the amplifier. Adjusting the wiper contact changes the resistance of the potentiometer, which in turn affects the gain of the amplifier. The same principle applies to many other circuit applications where the resistance of the trimmer potentiometer needs to be adjusted for a precise setting.

In addition to the adjustable output, the 3290P-1-200 trimmer potentiometer also features an insulation layer between the wiper contact and the resistive element. This prevents current from leaking between the two and helps maintain a precise setting even in high temperatures or high-frequency applications.

Conclusion

The 3290P-1-200 is a trimmer potentiometer used for precision applications, such as amplifier gain control, frequency adjustment, and other circuit applications. Its low cost, wide resistance range, insulation layer, and surface mount design make it an ideal choice for many circuits. With its flexibility and precision, the 3290P-1-200 is a great choice for any circuit application.
