The PDB241-E420K-103B0 is a 24 mm rotary potentiometer from Bourns' PDB24 Series designed for professional audio and commercial applications. It features a metal knurled shaft, carbon element construction, and is available with standard or high rotational life options (15,000 or 500,000 cycles minimum). The device offers a resistance range of 1 kO to 1 MO with ±20% tolerance, operates across -10°C to +70°C, and supports both linear and audio tapers with a mechanical angle of 300° ±5°. With a rotational torque of 20 to 200 g-cm, maximum operating voltage of 250 V (audio), and low rotational noise of 150 mV maximum, this potentiometer is ideal for sound processing equipment, guitar amplifiers, and various commercial applications requiring reliable volume or parameter control.
