HISTORICAL BACKGROUND: The 0402 chip resistor became increasingly important as electronic equipment moved toward smaller, more densely populated circuit boards. Panasonic's ERJ resistor families were developed for automated surface-mount production and became widely used in communications equipment, industrial controls, consumer electronics, automotive systems, and compact digital assemblies. A 240 ohm value is commonly useful for current limiting, transistor and logic interface circuits, signal conditioning, and general support networks where a precise 1% resistance value is desired.
