3386P-1-254LF is a 3/8" square single-turn cermet trimming potentiometer designed for industrial applications requiring precision resistance adjustment. This top-adjust model features a 250 kO nominal resistance value with ±10% standard tolerance, infinite resolution, and an adjustment angle of 280° nominal. The device operates over a temperature range of -55°C to +125°C with a temperature coefficient of ±100 ppm/°C, and is rated for 0.5 watts at 85°C. It exhibits excellent electrical stability with contact resistance variation of 2% or 3 ohms maximum, rotational life of 200 cycles, and dielectric strength of 900 VAC at sea level. The potentiometer is sealed, RoHS compliant with 100% tin-plated (LF) terminations, and features solderable pins for reliable PCB integration, making it suitable for instrumentation, audio equipment, and precision control circuits.
