Product Description
Product Overview
The 3224 Series 4 mm SMD Trimpot Trimming Potentiometer is a sealed, surface-mount cermet potentiometer designed for industrial applications. It features a compact 4mm square footprint that meets EIA/EIAJ/IPC/VECI SMD standard trimmer footprints, making it suitable for pick-and-place automated assembly. The design includes a flush adjustment and is sealed to withstand board wash processing. With low CRV (1%) and RoHS compliance, this trimmer is ideal for applications requiring precise adjustments in a small form factor.
