Additional Details:

The TMC3KJ series potentiometers from Noble are known for their robust construction and reliable performance. The 'B' taper refers to the linear relationship between the wiper position and the resistance value. The power rating and tolerance specifications should be verified by consulting the manufacturer's datasheet. The resistance value of 500 ohms allows for fine adjustment within circuits requiring lower impedance matching or current limiting.
