PRS12R-2125S-103B1 is a 12 mm rotary metal shaft dual-potentiometer designed for audio and linear taper applications with a resistance value of 10 kO. This component features a mechanical angle of 300° ± 5°, a power rating of 0.05 W, and a maximum operating voltage of 50 V AC / 10 V DC, with an insulation resistance of 100 megaohms minimum at 250V DC. The potentiometer offers various metal shaft options (flat, knurled, or slotted), horizontal and vertical mounting configurations, and PC pin layout for board mounting. It operates reliably over a temperature range of -10°C to +70°C with a minimum rotational life of 10,000 cycles, making it suitable for audio equipment, consumer electronics, and industrial control applications where precise resistance adjustment is required.
