PCW1J-C28-BAB103L is a single-turn panel control potentiometer featuring a compact 22 mm square slimline design with space-saving construction. The device offers a standard resistance range from 500 ohms to 1 megohm for linear tapers, with a total resistance tolerance of ±20% and independent linearity of ±5%. It features an effective electrical angle of 270° ± 5°, contact resistance variation of 7% of total resistance, and dielectric withstanding voltage of 1,000 VAC minimum at sea level. The potentiometer is available with PC pin or solder lug terminals, metric shaft and bushing options, and mounting brackets, making it suitable for audio equipment, instrumentation panels, and industrial control applications where compact panel-mounted potentiometers are required.
