The 3329P-1-203 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. The 3329P-1-203 is RoHS compliant, listed on the QPL for MIL-PRF-22097 and MIL-PRF-39035, and is ideal for precision trimming applications in industrial electronics, instrumentation, and sealed environments requiring reliable adjustment and long-term stability.
