The 3224W-2-203E is a 4 mm surface-mount trimming potentiometer (Trimpot) designed for industrial applications requiring sealed, halogen-free construction. It features a top-adjust style with multiturn cermet element, offering a standard resistance range of 10 ohms to 2 megohms with ±10% tolerance and essentially infinite resolution. The device is sealed to withstand board wash processing and meets EIA/EIAJ/IPC/VECI SMD standards, with a low contact resistance variation of 1% or 3 ohms maximum and 12 turns nominal adjustment angle. With an insulation resistance of 100 megohms at 500 VDC and dielectric strength of 600 VAC, this trimmer is ideal for precision calibration and tuning applications in industrial control systems, instrumentation, and consumer electronics requiring reliable performance in harsh environments.
