Kyocera develops small multilayer ceramic capacitors

Dec. 8, 2017

Kyocera Corp. today announced that it has developed new multilayer ceramic capacitors (MLCCs) for mobile device applications in a 008004 case size, among the world’s smallest for 008004 size MLCCs, based on research by Kyocera (as of November 2017). Measuring just 0.25 x 0.125 x 0.125 mm, Kyocera’s new CM01 Series MLCCs reduce space requirements by 60% in surface area and 75% in total volume as compared to conventional products, the company said. The new MLCCs are now available worldwide.

The trend toward smaller, more highly functional telecommunications equipment has increased component requirements within smartphones, wearables and related devices—creating particular demand for ultraminiature MLCCs to facilitate greater circuit densities. In response to this demand, Kyocera’s new CM01 Series’ ultra-compact size will help circuit designers create more capable and functional products. The new MLCCs feature tight tolerances on key specifications, with a Q-value which is 20% higher than conventional MLCCs (when compared to Kyocera’s conventional MLCCs in a 01005 case size) to meet the rising demand for highly efficient power-amplifier modules. Kyocera said it will continue to develop innovative products that contribute to an expanding IoT society.

Kyocera said continuous improvements in its proprietary electrode printing and forming technologies enable the company to reduce these components’ space requirement by 60% in mounting area and 75% in total volume, as compared to the 01005 case size. These ultracompact MLCCs can thus contribute to the goal of delivering equivalent performance from smaller devices or delivering greater performance and functionality without increasing the circuit (or device) size.

With demand for ever-greater telecommunication bandwidth and data transfer speeds, improved power efficiency has become crucial, the company said. Power-amplifier modules require components with tight tolerances on key specifications, such as electrode dimensions, to optimize power use within matching circuits. Kyocera’s new MLCCs accomplish this while reducing energy consumption in ultrahigh-speed and high-capacity devices.
