If you search through an electrical engineering textbook, you probably aren’t going to find the phrase “gimmick capacitor” but every old ham radio operator knows about them. They come in handy when ...

When Ceramic Capacitors Go Bad – Aging. Capacitor Aging applies to all Class 2 ceramic capacitors as they are built of ferroelectric materials. C0G types (Class 1) do not exhibit this aging effect, ...

Out of all of the fundamental passive electronic components, capacitors are arguably the most abundantly used. In fact, it is hard to find a circuit board that does not have a capacitor on it and a ...

Choosing a capacitor for reliable performance in today’s automotive electronics requires an examination of several parameters. The performance characteristics of the various capacitor technologies ...

Single-cell EC capacitors can reach 50,000 + farads. Daniel O'Brien, North American Capacitor Corp., Greencastle, Ind. All capacitors consist of two metallic electrode plates separated by an ...

Last month's column explained that AC current flowing through an inductance reaches its peak amplitude after the voltage. Lagging current is characteristic of an inductive circuit. Capacitive circuits ...

The pioneering years in the history of capacitors was a time when capacitors were used primarily for gaining an early understanding of electricity, predating the discovery even of the electron. It was ...

Electrochemical capacitors, also called supercapacitors, store energy using either ion adsorption (electrochemical double layer capacitors) or fast surface redox reactions (pseudo-capacitors). They ...

In residential and light commercial HVACR, we work with run capacitors every day, and you may have noticed that they fail quite often. Because of this, many companies are beginning to integrate ...

One of the most common parts to fail on a single-phase HVAC system is a run capacitor, so much so that we sometimes refer to junior techs as “capacitor changers.” While capacitors may be easy to ...

You can make all sorts of different types of inductors, but the most common type is cylindrical coil of wire---a solenoid. When current runs through the first loop, it creates a magnetic field that ...
