The 3329H-1-254LF is a 1/4" round single-turn cermet industrial trimming potentiometer (Trimpot) manufactured by Bourns with sealed construction and 100% tin-plated RoHS-compliant terminations. It features a standard resistance of 250 kO with ±10% tolerance, an adjustment angle of 240° nominal, and infinite resolution for precise voltage and resistance adjustability (±0.05% voltage, ±0.15% resistance). 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 at 500 VDC, and dielectric strength of 600 VAC at sea level. This potentiometer is ideal for precision trimming applications in industrial electronics, instrumentation, and control systems where reliable adjustment and environmental sealing are required.
