The 3339W-1-103LF is a four-turn cermet trimming potentiometer featuring a 10 kO resistance value with ±10% tolerance and RoHS-compliant 100% tin-plated terminations. It employs a unique planetary drive mechanism that enables precise wiper setting of a multiturn adjustment in a compact single-turn package size, with an effective travel of 4 turns nominal and infinite resolution. The device operates across a temperature range of -55°C to +150°C with a power rating of 0.5 watts at 85°C, insulation resistance of 1,000 megohms at 500 VDC, and dielectric strength of 600 VAC at sea level. Its sealed construction, side-adjust style, and solderable pins make it suitable for precision trimming applications in industrial instrumentation, signal conditioning circuits, and equipment requiring reliable long-term performance in demanding environments.
