Murata Electronics Designs Thin Embedded Capacitor For Substrates

Murata Electronics North America introduced the GRU series, described as the world’s thinnest embedded monolithic capacitor for substrates. Using advanced ceramic technology, the new 0402 size capacitor, measuring only 1.0 x 0.5 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 dielectric material expertise to achieve what is described as the world’s lowest profile at 150µm with a sophisticated external electrode formation to reduce the component’s thickness, while simultaneously providing a capacitance of 0.1µF. The built-in feature also enhances equipment performance by reducing wiring inductance.

"Murata’s focus on research and development helps us design the next generation of mounting methods," said Mark Waugh, Senior Product Manager for Murata Electronics North America. "The GRU series is the perfect example of improvements in materials technology that give our customer’s uncompromised quality in a miniature, innovative package for building into mobile device substrates."

Other benefits of the 0402 sized capacitor include a rated voltage of 6.3Vdc and X5R dielectric. The design also provides reliable connectivity via plating by utilizing copper plated terminations that can withstand the build-up process.

The GRU series is available for $0.05 and lead times are approximately 12 to 14 weeks.
