Product Description
Product Overview
The Bourns 3224 series is a 4mm SMD Trimpot trimming potentiometer designed for surface mount applications. These sealed cermet potentiometers offer a low Contact Resistance Variation (CRV) of 1% and are halogen-free and RoHS compliant. Featuring a pick-and-place centering design with flush adjustment, they meet EIA/EIAJ/IPC/VECI SMD standard trimmer footprints. The 3224 series is suitable for industrial applications and can withstand board wash processing.
