802-9664 SPECTRA Precision Potentiometer

Review SPECTRA Precision Potentiometer 2k Ohm

The Spectra Precision POT-802-9664 is a high-performance 2-kilohm precision potentiometer designed for applications that require precise voltage division and control. This potentiometer is manufactured by Spectra Precision, a well-known brand in the field of metrology and measurement solutions.

This 3-terminal linear potentiometer features a 2-kilohm resistance range with a 10-turn rotary mechanism. Its precision-machined, carbon composition resistive element ensures accurate and consistent voltage division over the entire travel. The resistance value is factory-trimmed to achieve a maximum error of 1.0% at 25 C (77 F), making it suitable for demanding applications that call for high-precision voltage control.

The POT-802-9664 has a robust construction, with a corrosion-resistant, nickel-plated brass housing and a Teflon bushing for smooth, reliable operation. The potentiometer is also equipped with a detented mechanism, which provides 10 defined positions for precise setting and repeatability.

The operating temperature range for this precision potentiometer is from -40 C to 85 C (-40 F to 185 F), making it suitable for a wide range of environments. The maximum power rating is 1 watt, and the maximum voltage rating is 50 volts. The potentiometer also features a low current noise of less than 1 microvolt per root hertz, ensuring minimal interference and maintaining the precision of your measurement system.

In summary, the Spectra Precision POT-802-9664 is a high-precision, 2-kilohm potentiometer that offers accurate voltage division, a robust construction, and a wide operating temperature range. Its detented mechanism ensures repeatable settings, and its low current noise makes it an excellent choice for demanding applications that require high-precision voltage control.

The Spectra Precision POT-802-9664 is a 2-kilohm precision potentiometer designed for applications requiring high accuracy and stability. Let's examine its potential advantages and disadvantages to help you make an informed decision.

1. High Accuracy: With a tolerance of 0.1%, this potentiometer offers excellent accuracy for sensitive applications in fields such as laboratory instruments, test equipment, and industrial control systems.

2. Stable Performance: The temperature coefficient of resistance (TCR) is as low as 50 ppm/ C, which ensures that the potentiometer maintains a consistent resistance value over a wide temperature range.

3. Rugged Construction: The Spectra Precision POT-802-9664 is built with a robust design, making it suitable for harsh environments and industrial applications. The potentiometer is RoHS compliant and has a protective epoxy coating to prevent damage from moisture, dust, and other contaminants.

1. Cost: As a high-precision potentiometer, the POT-802-9664 comes with a higher price tag compared to standard potentiometers. This may not be an ideal choice for budget-conscious projects or applications.

2. Lower Power Handling: With a maximum power dissipation of 0.5 watts, this potentiometer is not suitable for applications with high power requirements.

3. Limited Rotational Angle: The potentiometer's rotational angle is limited to 300 degrees, which may not be sufficient for certain applications that require a full 360-degree rotation.

The Spectra Precision POT-802-9664 is a high-accuracy, stable, and rugged 2-kilohm precision potentiometer, making it an excellent choice for applications that demand high precision and stability, such as laboratory instruments, test equipment, and industrial control systems. However, its higher cost, limited power handling, and rotational angle may be drawbacks for some users.

If you're looking for a high-precision potentiometer for a sensitive application, the Spectra Precision POT-802-9664 is an excellent option due to its impressive accuracy, stability, and rugged construction. However, if your application does not require such high precision, a standard potentiometer with a lower price tag may be a more suitable choice. Always consider the specific requirements of your application when selecting a potentiometer.
