Engineers designing power electronics find that capacitors are needed for several functions, from energy storage to filters and decoupling. Different capacitor types are available, that at first sight ...

This tutorial explains how ceramic capacitor type designations, such as X7R and Y5V, imply nothing about voltage coefficients. Engineers must check the data to know, really know, how a specific ...

Ceramic capacitors are small, they don’t leak, they’re convenient, but they are downright strange. Certain types of caps will lose their capacitance depending on the voltage they’re operating at. If ...

Over the last 40 years, a series of misconceptions regarding mica capacitor applications has led novice users to consistently over-derate wound or rolled mica/epoxy dielectric capacitors. The mined ...

Lightweight, small-size, and high-power-density power converter systems, which use only switches and capacitors in their power stage, have no need for transformers or inductors in their design. This ...

Dialog Semiconductor has announced a 10A switched-capacitor voltage divide-by-two, that operates at up to 98% efficiency, hitting or exceeding 95% at 10A. Called DA9313, it can deliver over 50W from ...

Southern States CapSwitcher is a high-voltage capacitor switching device specifically designed to meet the power quality needs of today's electrical systems. This special purpose SF6 capacitor switch ...

How do those defibrillators you see on TV actually work? Surprise! Physics can explain! So, how do those defibrillators you see on TV actually work? Surprise! Physics can explain! Okay buckle up, ...

Kemet is aiming at fast-switching wide bandgap semiconductor (GaN or SiC) power supplies with high-voltage multi-chip ceramic capacitor assemblies. The parts, branded ‘KC-Link with Konnekt’, feature ...
