Limited availability. Please forgive us if we run out of stock. This series is a double-barreled variable resistor with a shaft diameter of 6 mm. Please check the specifications (numerical value) as there may be differences in the length of the axis even if the image photos are the same. Variable resistors vary in the relationship between the rotation angle of the axis and the change in resistance, and are usually A-curve, B-curve, and rarely C-curve. ○The A-curve is exponential and ideal for audio volume control (volume control). ○The B-curve is a linear change and is used to adjust the voltage of general equipment. ○The C curve is the reverse of the rotation direction of the A curve and is used to adjust the gain of the amplifier, etc. (Specifications)
