The 3862E-202-502HL is a 1/2" diameter single-turn panel control potentiometer manufactured by Bourns with a cermet resistive element and linear taper. It features a standard resistance range from 1 kO to 1 MO with ±5% tolerance (H taper), independent linearity of ±5%, and an effective electrical angle of 260° ±10°. The device offers excellent resolution and small diameter construction, with a contact resistance variation of ±3% or 6 ohms (whichever is greater). It is RoHS compliant and rated for 750 VAC minimum dielectric withstanding voltage at sea level, with an insulation resistance of 1,000 MO minimum at 500 VDC. This potentiometer is ideal for panel-mounted control applications requiring precise resistance adjustment in industrial equipment, audio systems, and instrumentation.
