The 3223J-1-502E is a surface-mount 3 mm square multiturn cermet trimming potentiometer designed for industrial applications requiring sealed, reliable adjustment. It features a 5 kO nominal resistance value (code 502) with ±20% standard tolerance, 11 turns of adjustment, and essentially infinite resolution for precise tuning. The device is sealed to withstand standard board wash processing and meets EIA/EIAJ/IPC/VECI SMD standard footprints, with a flush adjustment screw and top-adjust configuration compatible with automated pick-and-place assembly. Operating over a temperature range of -65°C to +150°C with a power rating of 0.125 W at 70°C, it delivers robust performance in industrial control systems, instrumentation, and precision calibration applications where compact size and environmental sealing are essential.
