3252X-1-203 BOURNS Potentiometers

Review BOURNS Trimming Potentiometers

The Bourns 3252x-1-203 series potentiometers are linear, three-terminal adjustable resistors designed for precision voltage division and current attenuation applications. These potentiometers offer a fixed 10 turn, 20 position rotation providing a total resistance range of 100 ohms to 2.03 kOhms. The 1/4 inch (6.35mm) diameter shaft is suitable for various mounting configurations, including PCB mounting, panel mounting, or knob mounting. The Teflon insulation material used in the winding provides excellent dielectric strength and thermal stability, making these potentiometers well-suited for high-reliability and high-performance applications. The wiper contact material is made of gold over nickel, ensuring reliable and stable electrical contact over an extended period. The Bourns 3252x-1-203 series potentiometers also feature low noise and low leakage current, making them suitable for use in audio and instrumentation applications. The potentiometers are RoHS compliant and can be ordered with various options, including different shaft lengths, knobs, and wiring configurations, to meet specific application requirements.

The Bourns 3252x-1-203 potentiometer is a linear, single-turn, and carbon composition type potentiometer. It is commonly used in various applications such as volume controls, gain controls, and resistance setting. Let's discuss some pros and cons of using these potentiometers in your projects.

1. Cost-effective: Carbon composition potentiomers like the Bourns 3252x-1-203 are generally less expensive than their counterparts, such as film or metal film potentiometers.

2. Durable: Carbon composition potentiometers are known for their robustness and longevity. They can withstand high temperatures, harsh environments, and rough handling.

3. Wide range of resistance values: These potentiometers are available in a wide range of resistance values, making them suitable for various applications.

1. Temperature coefficient: Carbon composition potentiometers have a relatively high temperature coefficient, which means their resistance value can change with temperature. This can cause issues in applications that require precise resistance values over a wide temperature range.

2. Non-linear response: Carbon composition potentiomers have a non-linear response, meaning the resistance value at the end of the potentiometer does not correspond to the setting of the shaft. This can lead to inaccuracies and issues with calibration.

3. Drift: Over time, carbon composition potentiometers can exhibit drift, which is a gradual change in resistance value. This can cause issues with the consistency and reliability of the device using the potentiometer.

In conclusion, the Bourns 3252x-1-203 potentiometer offers cost-effectiveness, durability, and a wide range of resistance values. However, it comes with drawbacks such as temperature coefficient, non-linear response, and drift.

If your project requires precise resistance values over a wide temperature range, you may want to consider alternative types of potentiometers like film or metal film potentiometers. However, if you're looking for a cost-effective and rugged solution, the Bourns 3252x-1-203 potentiometer could be an excellent choice for your application.
