The PDB182-K420K-203B is a dual-gang 17 mm rotary potentiometer from Bourns' PDB18 Series, designed for professional audio and consumer electronics applications. It features a metal knurled shaft with 18-tooth serration, vertical PC pin configuration (12.5 mm spacing), and a 420 kO resistance value with audio taper characteristic. The potentiometer operates over a temperature range of -10°C to +50°C with a maximum operating voltage of 150 V for audio applications and a power rating of 0.1 W per section. It provides a mechanical angle of 300° ±5°, rotational torque of 10 to 150 gf-cm, and a rotational life of 15,000 cycles, with a soldering condition of 260°C maximum within 3 seconds. This dual-section design is ideal for stereo audio control in amplifiers, mixers, synthesizers, car radios, and professional audio equipment where synchronized dual-channel adjustment is required.
