The 3329H-1-101LF is a 1/4" round single-turn cermet trimming potentiometer (Trimpot) manufactured by Bourns, designed for sealed industrial applications requiring precision resistance adjustment. This model features a 100 ohm resistance value with ±10% tolerance, infinite resolution, and an adjustment angle of 240° nominal, providing fine-tuned control over a wide mechanical range. The potentiometer operates across a temperature range of -55°C to +150°C with a temperature coefficient of ±100 ppm/°C, and is rated for 0.5 watt power at 85°C (300 volts maximum). It incorporates solderable pins for reliable circuit integration, a maximum torque of 5.0 oz-in, and meets MIL-PRF-22097 and MIL-PRF-39035 specifications with RoHS-compliant 100% tin-plated termination. The 3329H-1-101LF is ideal for precision calibration, signal conditioning, and circuit tuning applications in industrial equipment, test instrumentation, and sealed electronic assemblies where environmental protection and long-term stability are essential.
