jb capacitors company offers trimming potentiometers in a variety of sizes and precision levels. For example, the JBR-065 and JBR-063 trimming potentiometers include multi-turn options, requiring several turns of the adjustment screw to achieve the desired value. This design ensures exceptionally high accuracy. Please refer to the specifications below for more details.
