The ever-growing price of precious metals has promoted the widespread use of nickel and copper in the internal electrodes and end terminations of multilayer ceramic capacitors (MLCCs). While these base metal electrode (BME) capacitors are less expensive than capacitors made with palladium and silver/palladium, their unique production process produces an identifiable wear-out mechanism.
What is a capacitor!? This ebook introduces capacitors, the basic theory, and some terminology used in the industry.
This is a continuation of the TecForum and panel discussions at DesignCon 2005, Santa Clara, on the same topic held by Sanyo, Taiyo-Yuden, Cisco, Intel and SUN.
The last few years has seen a significant advancement in the design of high voltage X7R MLCC with higher capacitance that are resistant to arcing. The purpose of this paper is to explain how these work and their benefits. To do this we must first consider the different failure modes that can occur in X7R MLCC above 200V.
