The 3224J-1-105E is a 4 mm surface-mount trimming potentiometer (Trimpot) designed for industrial sealed applications requiring board wash processing compatibility. It features a 1 megohm resistance value with ±10% tolerance, essentially infinite resolution, and a low contact resistance variation of 1% or 3 ohms maximum. The device operates with a 12-turn nominal adjustment angle, 180 g-cm maximum torque, and maintains insulation resistance of 100 megohms minimum at 500 VDC. Its sealed design with J-hook configuration, combined with RoHS compliance and halogen-free construction, makes it suitable for precision trimming applications in industrial equipment, instrumentation, and consumer electronics requiring reliable performance in harsh manufacturing environments.
