The TMC3K-B6.8K-TR is a cermet trimming potentiometer manufactured by Noble. It's a small, adjustable resistor used for fine-tuning electronic circuits. The "B" indicates a linear taper, which means the resistance changes proportionally with the rotation of the adjustment screw. The "6.8K" represents a total resistance of 6.8 kiloohms.
