Murata Manufacturing Co. Ltd has developed what it touts as the world's first automotive grade monolithic ceramic capacitors. The GCQ series features high Q characteristics aimed at vehicle-to-vehicle and vehicle-to-infrastructure communication vehicle to X (V2X) applications.

V2X refers to direct communication between vehicles or between vehicles and infrastructure such as traffic lights. This technology is aimed at avoiding accidents such as collisions and realising a more efficient transport system. It is expected to play an important role in paving the way to the realization of fully autonomous driving in the future.

GCQ series

DSRC IEEE 802.11p is a V2X communication standard (communication frequency: 5.9GHz) intended mainly for use in North America and Europe, and high Q capacitors are in demand for DC filtering and RF matching in the 5.9GHz band. Murata has developed highly reliable automotive grade high Q capacitors to meet this need.

These high Q capacitors are AEC-Q200 conformable and suitable for V2X, ADAS, and other automotive communication applications. The self-resonance frequency of 5.9GHz (2.2pF model) is ideal for DC filtering under DSRC IEEE 802.11p. The internal electrodes are made of copper, which enables a high Q value at high frequencies and is ideal for matching applications.

The 50VDC GCQ series supports an operating temperature range of -55°C to 125°C and flaunts a capacitance range of 0.1pF to 47pF.

Offered in the 0402 size: 1mm x 0.5mm (T = 0.5mm), mass production is scheduled to commerce in 1H16. Sample shipments have begun.
