The 3329H-1-102 is a 1/4" round single-turn cermet industrial trimming potentiometer (Trimpot) manufactured by Bourns with a sealed design and 1,000 ohm resistance value. It features five standard terminal styles, infinite resolution, and an adjustment angle of 240° nominal with a mechanical angle of 260° nominal. The device operates over a temperature range of -55°C to +150°C with a power rating of 0.5 watt at 85°C (300 volts maximum), insulation resistance of 1,000 megohms minimum at 500 VDC, and dielectric strength of 600 VAC at sea level. This trimmer is ideal for precision circuit tuning and calibration applications in industrial electronics, instrumentation, and equipment requiring reliable, sealed potentiometer performance with tight tolerance control.
