The 3339P-1-101LF is a four-turn cermet trimming potentiometer manufactured by Bourns, featuring a 100 ohm resistance value with a unique planetary drive mechanism that enables precise wiper setting in a compact 5/16" round package. This sealed industrial-grade component offers ±10% resistance tolerance, infinite resolution, and adjustability of ±0.05% voltage and ±0.1% resistance, with an effective travel of 4 turns nominal. The device operates across a temperature range of -55°C to +150°C, provides 0.5 watt power rating at 85°C, and features 1,000 megohms minimum insulation resistance at 500 VDC with 600 VAC dielectric strength at sea level. The RoHS-compliant LF termination uses 100% tin plating, making it suitable for precision trimming applications in instrumentation, data acquisition, and industrial control systems where reliable adjustment and environmental sealing are essential.
