The dielectric constant (Dk) of plastic or dielectric or insulating material can be defined as the ratio of the charge stored in an insulating material placed between two metallic plates to the charge that can be stored when the insulating material is replaced by vacuum or air. It is also called as electric permittivity or simply permittivity.

Many engineers believe that there is a single inductor value that should be used for a given design. They may have read an application note, or a textbook, that sets the value of the current ripple in a buck converter, for example. I would caution becoming complacent in this technique.

CAP-XX (LSE: CPX), a leader in supercapacitors that deliver peak power to support or replace batteries, today announced it has developed the industry’s first 3V thin, prismatic supercapacitors. The company will deploy its 3V technology first in the thin prismatic form to meet the demand for small, inexpensive, energy-efficient power solutions for thin wearables, key FOBs and other IoT devices. CAP-XX will then integrate the 3V technology into its larger prismatic supercapacitors, automotive modules, and other products for high-energy, high-power applications.

The MLCC capacitor is one of the most widely used passive components today. Approximately 1000 billion multilayer ceramic capacitors are produced per year. Manufacturers have improved the electrical performance of these passive components through incremental progress in design, manufacturing methods, and materials.

The automotive electronics industry has responded to automotive application challenges by defining a component stress-test standard for passive components known as AEC-Q200. It includes a set of tests, some drawn from other standards bodies, which a device must pass for it to be qualified to AEC-Q200. What is this about?

Scientists from Skoltech, Moscow State University (MSU) and Moscow Institute of Physics and Technology (MIPT) have proposed a new approach to replacing carbon atoms with nitrogen atoms in the supercapacitor’s crystal lattice and developed a novel capacity enhancement method based on carbon lattice modification with the aid of plasma. Their findings can help create the next generation of power sources for portable electronics. The results of their study were published in Nature – Scientific Reports.

Revenues fell to $101.2 billion in Q1,;down 12.9% from $116.2 billion in Q118. This represented the largest y-o-y quarterly decrease since the second quarter of 2009. Memory drove the sales to plunge exacerbated by excess inventory and falling demand from key end markets. If memory were excluded from total semiconductor revenue, the market would have declined by ~4.4% on a y-o-y basis.
