Abstract: The rate of change in the satellite world is accelerating and along with that comes the changes needed for power supplies onboard. This article provides a high-level view of the emergence of base metal electrode (BME) multilayer ceramic capacitors (MLCCs) for satellite applications. After providing some background on MLCCs and the development of their electrode materials, this article describes the advances in component materials, construction and fabrication techniques, and the track record in automotive and other sectors that have proven the reliability of BME MLCCs. Then the size advantages which motivate the use of these capacitors in space are discussed. The rest of this article reviews the reliability studies that AVX has performed to qualify BME MLCCs for space,

Abstract: Over the years, ceramic capacitors have been used interchangeably with tantalum in many applications, class II ceramics being the one electrostatic technology that can achieve the high capacitance values typically associated with electrolytic capacitors. But because of MLCC shortages, we are currently at a point where designers are reconsidering electrolytic capacitors for applications that had switched to class II ceramic in recent years. However, migrating circuit designs from MLCCs to tantalum electrolytics requires an understanding of multiple issues that impact how these different styles of capacitors will perform in the intended application. This article discusses the key parameters that differentiate these two capacitor categories in the various roles they play in power supply applications (bypassing, filtering, decoupling, bulk hold
Abstract: Electronic components in safety-relevant systems such as medical devices, aircraft controls, airbags or driver assistance systems must meet the highest requirements in terms of reliability and safety. This also applies to passive components such as ceramic capacitors.

End systems are evolving at faster paces and typically involve a common theme where increasingly complex electronic content have to work at faster speeds, in smaller packages, powered by lower voltages. That trend shows little sign of slowing since the sub-components used in creating systems, whether passive device or active, are shrinking due to improved material purity, new device processing and advances in manufacturing.
