3386X201-10

200OHM Cermet Trimming Potentiometer manufactured by Bourns Inc. This precision electro-mechanical variable resistor features a 3/8-inch square package configuration, an extra-low profile single-turn pin orientation ("3386X"), and a nominal total resistance value of 200 ohms (indicated by the "201" code format). It functions by sliding a precious metal wiper across a highly stable cermet (ceramic-metal) resistive track via a mechanical adjustment screw, allowing operators to execute micro-adjustments to circuit parameters like gain tuning, reference voltage balancing, and offset nulling. It was universally deployed as a field-calibration component inside industrial instrumentation meters, laboratory power supplies, medical diagnostic systems, and audio synthesis gear.
