The 3224J-1-201E is a 4 mm SMD Trimpot® trimming potentiometer designed for surface-mount applications requiring sealed, industrial-grade performance. It features a standard resistance range of 10 ohms to 2 megohms with ±10% tolerance, essentially infinite resolution, and a contact resistance variation of 1% or 3 ohms maximum. The device is rated for 12 turns nominal adjustment angle with a low coefficient of resistance variation (CRV) of 1%, and includes a mechanical stop with wiper idle design. With RoHS compliance, halogen-free construction, and UL94V0 flammability rating, this trimmer is sealed to withstand board wash processing and features pick-and-place centering design with flush adjustment. It is ideal for precision tuning applications in industrial electronics, instrumentation, and consumer devices where reliable, sealed potentiometer performance is required.
