The PDB182-K425K-103A is a dual-section 17 mm rotary potentiometer designed for professional audio and pro audio equipment applications. This potentiometer features a metal knurled shaft with 18-tooth serration, PC pins vertical down-facing configuration (12.5 mm), and no detent positions for smooth continuous rotation. It incorporates a carbon element with audio taper characteristics, offering a standard resistance tolerance of ±20% and residual resistance of 1% maximum. The device 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 0.06 W for dual-section configuration. With a mechanical angle of 300° ±5°, rotational torque of 10 to 150 gf-cm, and rotational life of 15,000 cycles, this potentiometer is well-suited for mixing consoles, synthesizers, drum machines, and other professional audio equipment requiring reliable, smooth control.
