Film Capacitors Characteristics and Uses in Power Applications

By EDN Posted On 18.4.2019

Source: EDN article

by Rudy Ramos.

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 might seem equivalent in their headline ratings of capacitance and voltage, but would not perform equally. Incorrect selection can lead to, at best, an expensive ‘over-engineered’ solution and, at worst, an unreliable or unsafe product. (more…)

Negative capacitor enable higher voltage, high efficient system while operating at lower voltage

By Science Daily Posted On 9.4.2019

source: Science Daily news

by DOE/Argonne National Laboratory, original written by Jared Sagoff. Researchers have created a permanent static ‘negative capacitor,’ a device believed to have been in violation of physical laws until about a decade ago. Newly devised static negative capacitor could improve computing and yield more energy-efficient computers. (more…)

High CV MLCC DC BIAS and AGEING Capacitance Loss Explained

By European Passive Components Institute Posted On 1.3.2019

Source: Original EPCI article

by: Tomas Zednicek, EPCI

MLCC capacitors are dominating today’s capacitor market enabling high grade of electronics miniaturization. The continuous downsizing and use of higher and higher dielectric constant materials for MLCC class II capacitors has however resulted in worsening of some electrical parameters stability such as capacitance drop at operating conditions. Thus, in consequence, what can be considered as an enabling technology for consumer and wearable applications may pose some risk if used in critical applications such as automotive, safety, medical or industrial sector, that are also in need for continuous miniaturization.
