Product Overview
The 3224 Series 4 mm SMD Trimpot Trimming Potentiometer is a surface-mount, multiturn cermet potentiometer designed for industrial applications. It features a sealed construction to withstand board wash processing, a pick-and-place centering design with flush adjustment, and meets EIA/EIAJ/IPC/VECI SMD standard trimmer footprints. Available in top and side adjust styles with J-hook and gull-wing terminations, these potentiometers offer low CRV (1%) and are RoHS compliant and halogen-free. They are suitable for a wide range of resistance values and environmental conditions.
