The 3862C-202-502AL is a 1/2" diameter single-turn panel control potentiometer manufactured by Bourns with a cermet element and 5 kO resistance value. It features a linear taper with ±10% tolerance, an effective electrical angle of 260° ±10°, and independent linearity of ±5%. The potentiometer has a plain 1/4" bushing (6.35 mm diameter × 6.35 mm length), solder lug terminals with slotted end shaft, and operates with a standard resistance range from 1 kO to 1 MO. This compact design with good resolution and wide resistance range makes it suitable for audio equipment, instrumentation panels, and control applications requiring reliable, smooth adjustment with minimal contact resistance variation.
