The 3329H-1-202 is a 1/4" round single-turn cermet industrial trimming potentiometer (Trimpot) manufactured by Bourns with sealed construction and five standard terminal styles. It features a resistance range of 10 ohms to 1 megohm with ±10% standard tolerance, infinite resolution, and an adjustment angle of 240° 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 sealed equipment where reliability and environmental protection are required.
