HISTORICAL BACKGROUND: Panasonic traces its origins to Osaka, Japan in 1918, when Konosuke Matsushita established the company that developed into one of Japan's most important electronics manufacturers. Along with its well-known consumer products, Panasonic built an extensive electronic-components business supplying resistors, capacitors, relays, switches, sensors, batteries, and other components for industrial, automotive, communications, audio, and consumer equipment. The ERJ family represents Panasonic's long-running thick film chip resistor technology developed for automated surface-mount assembly. The 0603 format became one of the electronics industry's most widely used SMD sizes because it combines compact dimensions with practical handling and useful electrical performance. Panasonic is a Japanese-origin manufacturer, while the original Mouser label on this specific package identifies China as the country of manufacture.
