Product Overview
The ERJ series chip resistors are compact and lightweight, featuring high reliability due to their alloy thick film and three-layer electrode construction. They are supplied in tape packaging suitable for automatic mounting machines and are compatible with reflow and dip soldering. These resistors comply with IEC 60115-8, JIS C 5201-8, and EIAJ RC-2134B standards. Most series are AEC-Q200 certified (excluding ERJXG) and RoHS compliant.
