Some of the AC power consumed by inductive loads is used to maintain magnetic reversals due to phase shift between current and voltage. This energy can be considered as wasted energy since it is not used in performing useful work. Power factor correction circuits are used to minimize reactive power and enhance the efficiency with which inductive loads consume AC power. Capacitors are essential components in power factor compensation circuits, and this article will explore some design considerations when using these components for power factor correction. (more…)

Capacitors are used in electronic circuits for a wide range of applications including coupling, timing, filtering, decoupling, and wave shaping. These passive components come in a wide array of shapes, sizes, and designs, and it is usually not easy to identify a component that meets the specific requirements of an application. In most electronic circuits, the overall performance of a circuit is greatly determined by the choice of capacitors. (more…)

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…)

Why low ESR matters in capacitor design

By Capacitor Faks and EPCI Posted On 11.2.2019

Source: Capacitor Faks blog, EPCI

by Anthony Kenny (Capacitor Faks) and Tomas Zednicek (EPCI). A practical capacitor is a non-ideal component. Its circuit model contains series inductance (ESL) and series resistance (ESR). Although equivalent series resistance is often shown in circuit models as a constant value, it varies depending on operating conditions. ESR is resistance from a combination of energy loss mechanisms under specific operating conditions. (more…)

Effects of ESL on capacitor performance

By Capacitor Faks and EPCI Posted On 8.2.2019

Source: Capacitor Faks blog

Capacitors are widely used in electronic circuits for storing and managing energy. Typical applications include filtering, decoupling, energy storage, and tuning. Some applications such as decoupling demand low impedance, high ripple current capability, and excellent surge performance. Inductance is one of the key parameters to consider when selecting a capacitor for high speed digital circuits. (more…)
