The PTV09A-2020F-A103 is a 9 mm potentiometer from Bourns' PTV09 Series designed for professional audio and consumer electronics applications. It features a linear audio taper with a standard resistance range of 1 kO to 1 MO, ±20% tolerance, and an insulated flat-type shaft with a 20 mm standard length. The device operates over a temperature range of -10°C to +50°C with a maximum operating voltage of 20 VDC or 50 VAC, and a power rating of 0.05 W. It exhibits a mechanical angle of 280° ±10°, rotational torque of 10 to 100 g-cm, and a rotational life of 10,000 cycles, with a sliding noise specification of 100 mV maximum. This potentiometer is ideal for commercial communications equipment, portable electronics, amplifiers, mixers, synthesizers, and consumer appliances where reliable volume or parameter control is required.
