Available in capacitance values from 0.1 to 47pF, the GCQ series of high Q MLCCs has been introduced by Murata for automotive V2X applications. Featuring 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 V2I and 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 (1.0×0.5mm) and operates over a temperature range from -55 to +125°C. The high Q rating is achieved by the use of copper internal electrodes.
The GCQ series is now sampling and mass production is scheduled to start during the first half of 2016.
