Murata has introduced the GRU series, what it says is the world's thinnest embedded monolithic capacitor for substrates. Using advanced ceramic technology, the new 0402 size capacitor, measuring only 1.0mm x 0.5mm x 0.15mm, is built into the substrate for placement below integrated circuits (ICs) and other electronics.

The GRU series was developed using Murata's leading-edge dielectric material expertise to achieve the world's lowest profile at 150µm with a sophisticated external electrode formation to reduce the component's thickness. Since this capacitor is designed to be mounted within the PCB substrate, it also enhances equipment performance by reducing wiring inductance.

The GRU series is available in capacitance values of 100pF, 1nF and 0.1µF. Other benefits of the 0402 sized capacitor include a rated voltage of 6.3Vdc and X5R dielectric. The GRU series' copper plated terminations are designed for copper via connection and provide reliable connectivity since they can withstand the build-up process, and the devices have no polarity. The devices are available in embossed tape and reel packaging for automatic placement and can withstand the operating temperature range -55 to +85°C.
