Product Description
Product Overview
The 3224 4mm SMD Trimpot Trimming Potentiometer is a sealed, cermet, surface-mount potentiometer designed for industrial applications. It features a pick-and-place centering design with flush adjustment, meeting EIA/EIAJ/IPC/VECI SMD standard trimmer footprints. This product is halogen-free and RoHS compliant, offering low contact resistance variation (CRV) of 1% and a sealed construction to withstand board wash processing. It is suitable for a wide range of resistance values from 10 ohms to 2 megohms.
