3386P-1-500TLF is a 3/8" square single-turn cermet trimming potentiometer designed for industrial applications requiring precise resistance adjustment. This top adjust style potentiometer features a 50 ohm resistance value with ±10% tolerance, 280° nominal adjustment angle, and infinite resolution for fine-tuning. It offers a power rating of 0.5 watt at 85°C, operates over a temperature range of -55°C to +125°C, and includes 100% tin-plated (lead-free) terminations for RoHS compliance. The sealed construction provides protection against environmental factors, with vibration resistance up to 30G and shock resistance up to 100G. Common applications include calibration, tuning, and adjustment circuits in industrial and electronic equipment where reliable, repeatable resistance settings are required.
