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 ...

When designers think of passive components, they think of manufacturing tolerances for inductors and capacitors that are typically ± 20% or ± 10%. That's okay in theory, but not when these components ...

According to the IEEE Standard Dictionary of Electrical and Electronic Terms, power factor (PF) is defined as the ratio of the circuit power (watts) to the circuit volt-amperes. This is described by ...

Because of their high ESL compared to ceramic, tantalum capacitors are not the optimum choice for high frequency decoupling. Paralleling tantalum capacitors for bulk capacitance and ceramic for high ...

This circuit for measurement of inductance and capacitance can be used to test whether the values of inductors and capacitors quoted by the manufacturer are correct. The principle used in the circuit ...

First, let's define a capacitor: It is an electromechanical device capable of storing electrical energy (electrons). It differs from a battery, as a battery produces electrical energy as a by-product ...

Vishay Intertechnology is extending its 193 PUR-SI series of miniature snap-in power aluminium electrolytic capacitors. There ...

When it comes to the most typical cause of poor power factor in a facility, motor inductance is a likely culprit. The problem worsens when motors are not loaded to their full capacity. Harmonic ...

Your phone died. Again. In these scenarios, who among us has not dreamed the dream of a future where our devices charge instantly and last forever. As capacitors—or even more exciting, ultracapacitors ...
