3214W-1-202E Trimmer Potentiometers by Bourns, Inc.

The "3214W-1-202E" is a specific model of a potentiometer manufactured by Bourns, Inc., a well-known company specializing in electronic components. This particular component is part of their 3214 series, which is recognized for its reliability and versatility in various applications.

Detailed Description:

1. Type: The 3214W-1-202E is a linear potentiometer, which means it provides a variable resistance that changes linearly with the rotation of its shaft. This makes it suitable for applications requiring precise control over voltage or current.

2. Resistance Value: The "202" in the model number indicates a resistance value of 20 kΩ (20,000 ohms). This is a common resistance value used in many electronic circuits, allowing for a wide range of applications.

3. Taper: The "W" in the model number signifies that it has a linear taper. This means that the resistance changes uniformly as the shaft is turned, providing a consistent response throughout its range.

4. Physical Dimensions: The potentiometer typically features a compact design, making it easy to integrate into various electronic devices. The dimensions are generally around 32 mm in length and 14 mm in diameter, but specific measurements can vary slightly based on the exact configuration.

5. Shaft Type: The 3214W-1-202E usually comes with a standard shaft that can be either knurled or smooth, allowing for easy attachment of knobs for user interaction. The shaft length is designed to fit standard panel thicknesses.

6. Mounting Style: This potentiometer is designed for panel mounting, which means it can be securely attached to the front of a device, allowing users to easily adjust the resistance.

7. Terminals: The component typically features three terminals: one for the wiper (the adjustable contact) and two for the fixed ends of the resistive element. These terminals are usually solderable, facilitating easy integration into circuit boards.

8. Temperature Range: The 3214W-1-202E is designed to operate effectively across a wide temperature range, typically from -55°C to +125°C, making it suitable for both consumer and industrial applications.

9. Applications: This potentiometer is commonly used in audio equipment, consumer electronics, industrial controls, and instrumentation, where precise adjustments are necessary.

10. Durability: Bourns is known for producing high-quality components, and the 3214W-1-202E is no exception. It is designed to withstand mechanical wear and tear, ensuring longevity and reliability in various environments.
