PTV111-3420A-A103 is a 12 mm rotary potentiometer featuring a carbon element resistive element with an insulated shaft and snap-in clip mounting. It offers a linear taper with a standard resistance range of 1 kO to 1 MO and ±20% tolerance, with a maximum residual resistance of 1% and mechanical angle of 300° ±5°. The device operates over a temperature range of -10°C to +50°C with a power rating of 0.05 W and maximum operating voltage of 50 VAC or 20 VDC, featuring a rotational torque of 20 to 200 g-cm and detent torque of 30 to 300 g-cm with 15,000 cycles rotational life. This potentiometer is ideal for audio equipment, amplifiers, synthesizers, and consumer electronics where reliable volume control and signal adjustment are required.
