The 3224X-1-201E is a surface-mount 4 mm square multiturn cermet trimming potentiometer designed for industrial applications requiring sealed construction to withstand board wash processing. It features a 200 ohm resistance value with ±10% tolerance, 12 turns of adjustment, and a contact resistance variation of 1% or 3 ohms maximum, delivering low cost of resistance variation (CRV) of 1%. The device is RoHS compliant and halogen-free, with a top-adjust configuration and adjustment slot dimensions of 0.6 mm wide by 0.5 mm deep. This trimmer is ideal for precision calibration and tuning applications in sealed environments where reliability and repeatability are essential, such as industrial control systems and test equipment.
