Review BOURNS Lot Of Potentiometer Precision 10k Ohms Turn Nnb

The Bourns 6639S-464-102 is a high-precision 10,000-ohm (10k) potentiometer designed for applications where precise voltage control is essential. This linear potentiometer features a carbon composition resistive element, which provides excellent stability and low TCR (Temperature Coefficient of Resistance).

Measuring 3.5 inches (88.9mm) in length and 0.75 inches (19.1mm) in diameter, this potentiometer is suitable for various industrial, laboratory, and electronic projects. Its smooth, easy-to-operate shaft is 0.25 inches (6.35mm) long, making it a popular choice for volume control in audio equipment.

The Bourns 6639S-464-102 potentiometer offers a maximum power rating of 0.25 watts and a maximum voltage rating of 1,000 volts. Its operating temperature range is from -40 C to 125 C (-40 F to 257 F), ensuring reliable performance in a wide range of environments.

This potentiometer features a wiper with a 0.1% tolerance, allowing for precise voltage adjustment. It also includes a rotary switch with three terminal configurations: linear, logarithmic, and voltage divider. The linear configuration offers a straight voltage relationship between the wiper position and the output voltage. The logarithmic configuration provides a voltage output that increases at a logarithmic rate as the wiper is rotated. The voltage divider configuration divides the input voltage into two equal parts, with one portion being fixed and the other portion being variable.

The Bourns 6639S-464-102 potentiometer is housed in a rugged, epoxy-coated metal case with a bushing and locknut for secure mounting. It comes with a 0.1 inch (2.54mm) shaft diameter and a 0.025 inch (0.635mm) shaft height. This potentiometer is leaded, with 3 wires (102 color code) exiting the side of the housing.

In summary, the Bourns 6639S-464-102 is a versatile and high-precision 10k potentiometer with a carbon composition resistive element, suitable for various industrial, laboratory, and electronic applications where precise voltage control is required. It offers a smooth, easy-to-operate shaft, multiple terminal configurations, and a rugged, epoxy-coated metal housing for reliable performance in a wide range of environments.
