The TMC2KJ-B3.3K-TR is a trimmer potentiometer manufactured by Noble. It's a small, adjustable resistor used for fine-tuning circuits. It features a resistance of 3.3 kilohms (3,300 ohms) and a B taper, indicating a logarithmic change in resistance as the adjustment screw is turned. The 'TR' suffix indicates that it is packaged on tape and reel for automated assembly.
