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…)

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…)

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…)

by Johanson Technology.

For many high power RF applications, the ‘Q factor’ of embedded capacitors is one of the most important characteristics in the design of circuits. This includes products such as cellular/telecomm equipment, MRI coils, plasma generators, lasers and other medical, military and industrial electronics. (more…)
