The GGW0603UCR18JGT is an inductor, or chip antenna, with a surface-mount 0603 form factor and RoHS (Restriction of Hazardous Substances) compliant construction. It is manufactured by Guoju, a Chinese electronic component company, and has a highly reliable 18 nH inductance. Its small size and low profile make it ideal for use in space-restricted designs and applications that require a high level of miniaturization. Its operating temperature range is -40°C to +85°C and its rated voltage is 50V DC. This component is typically used in wireless communication, radar, navigation, and other applications, where its high-Q characteristics provide an ideal solution for the transmission or reception of radio waves.
