The 3224J-1-204E is a 4 mm SMD Trimpot® trimming potentiometer designed for surface-mount applications requiring sealed, industrial-grade performance. It features a multiturn cermet element with a standard resistance range of 10 ohms to 2 megohms, ±10% tolerance, and essentially infinite resolution. The device is sealed to withstand board wash processing and incorporates a pick-and-place centering design with flush adjustment capability. With a low contact resistance variation of 1% or 3 ohms maximum, 12-turn adjustment angle, and operating temperature range of -65°C to +150°C, this trimmer is well-suited for precision calibration and tuning applications in industrial electronics, instrumentation, and control systems. The product is RoHS compliant and halogen-free, meeting EIA/EIAJ/IPC/VECI SMD standards.
