High-Q MLCC targets automotive V2X applications

Murata has introduced the GCQ series of high-Q monolithic ceramic capacitors (MLCCs) aimed at automotive V2X applications. Available in capacitance values from 0.1pF to 47pF, a C0G temperature characteristic and a rated voltage of 50VDC, the series conforms to the requirements of the automotive components standard AEC-Q200 and suits use in V2X, ADAS and other automotive applications. Meeting the needs of the DSRC IEEE 802.11p V2X communications standard, for both vehicle-to-infrastructure (V2I) and vehicle-to-vehicle (V2V) applications, mainly in Europe and North America using the 5.9GHz band, the GCQ series can be used for DC filtering and RF matching. In particular, the self-resonance frequency characteristic of the 2.2pF device suits DC filtering according to the DSRC IEEE 821.11p requirement. The GCQ series is packaged in a 0402 size (1mm x 0.5mm) and has an operating temperature range from -55C to + 125C. The device's high-Q rating is achieved by the use of copper internal electrodes.
