Murata Introduces World's First Surface Mount Multilayer Ceramic Capacitors That Meet New Capacitance Standard

GW Series Capacitors Comply with JEITA RCX-2326

Smyrna, GA - Murata Electronics North America, a world-leading innovator in electronics and the largest global supplier of ceramic passive components, today introduced the world's first surface mount multilayer ceramic capacitor that meets the Japan Electronics and Information Technology Industries Association (JEITA) RCX-2326 standard. This standard regulates capacitance under real-world operating conditions and was adopted because capacitance in ferroelectric materials, when used in voltage dependent ceramic capacitors, can vary between the nominal capacitance and the capacitance under actual in-service circumstances. Murata's new GW series, which is available in three options - length width (LW) reverse two terminal construction, three terminal construction and two terminal construction - is the first on the market to meet these important standards by guaranteeing the capacitance of 100µF under actual operating conditions.

The LW reverse, three terminal and conventional two terminal constructions, all provide large capacitance and low impedance. This advanced design leads to significant downsizing in equipment as it reduces the number of different components required. For example, in LW reverse construction, the capacitor's electrodes are oriented parallel to the long side of the capacitor. As a result of these structural changes, low impedance is achieved over a very wide frequency band. In addition, the LW reverse design also lowers inductance.

As a result of the GW series high capacitance, low impedance and component reduction ability, it is ideal for use in decoupling capacitor applications in power supply circuits of low voltage driven devices, integrated circuits (IC), central processing units (CPUs) CPUs, large scale integration (LSIs) and field programmable gate arrays (FPGAs).

"Designing quality components to attain the most accurate performance is what Murata does best," stated Kazuyuki Kubota, marketing manager, capacitor components for Murata Electronics North America. "The GW series capacitors achievement of being the first to market that meets the JEITA RCX-2326 standard is a testament to this vision."

The two terminal product (global part number GWM32RJ10E107Y), measures 3.2mm x 2.5mm x 1.8mm and is available for $0.35. The LW reverse (global part number GWL4VCJ10E107Y) is 2.0mm x 4.0mm x 1.8mm and costs $0.50 and the three terminal (global part number GWF4VCJ10E107y) is $0.70 with the dimensions of 4.0mm x 2.0mm x 1.5mm. All GW series capacitors provide 100µF capacitance with a rated DC voltage of 2.5V. The operating temperature range is -25°C to 105°C. The lead-time is 12 weeks.
