Dual volume A-weighted 50kΩ R1610G-QB1-A503 1 piece

This series is a double variable resistor with a shaft diameter of φ6mm. Even if the image is the same, the shaft length may differ, so please check the specifications (numbers). There are various types of variable resistors depending on the relationship between the rotation angle of the shaft and the change in resistance, and A curve, B curve, and rarely C curve are used. ○ A curve is an exponential change and is ideal for audio volume control. ○ B curve is a linear change and is used for voltage adjustment of general equipment. ○ C curve is the opposite of the A curve and is used for amplifier gain adjustment. The A characteristic is an exponential change in the resistance value of the tap with respect to the rotation angle, and the B characteristic is a linear change. A characteristic is usually used for volume control. B characteristic can also be used electrically, but when you turn the knob, the sound suddenly becomes louder from a certain position. There are several other types of C characteristic and other types classified by the relationship between the rotation angle and the resistance change, but A and B are the most popular.
