The PDB181-E420K-103B is a 17 mm rotary potentiometer from Bourns' PDB18 Series, designed for professional audio and consumer electronics applications. It features a single-section design with solder lugs (E configuration), no detents (4 option), a 20 mm knurled metal shaft (K style), and a 420 kO resistance value with ±20% tolerance. The potentiometer operates over a temperature range of -10°C to +50°C with a maximum operating voltage of 150 V for audio taper and a power rating of 0.1 watt. It provides a mechanical angle of 300° ±5°, rotational torque of 10 to 150 gf-cm, and is rated for 15,000 rotational cycles with RoHS compliance. This potentiometer is ideal for audio/TV sets, car radios, amplifiers, mixers, synthesizers, and other consumer applications requiring reliable volume or tone control.
