There was a recent news item regarding a teenager's project to use a super capacitor as a quick-charging energy storage device. The primary claim is that this could be used to fully charge a phone in ...

Yi Liu (left) and Zongliang Xie fabricate film capacitors from polymers and then evaluate both the polymers and capacitors at the Molecular Foundry. The Department of Energy’s Lawrence Berkeley ...

(Phys.org)—Capacitors are widely used in electrical circuits to store small amounts of energy, but have never been used for large-scale energy storage. Now researchers from Japan have shown that the ...

Vintage electronics and capacitor replacements tend to go hand-in-hand. Why? Because electrolytic capacitors just don’t last, not the way most other components do, anyway. The metal terminal ring and ...

If you build electronic circuits on a regular basis the chances are you will have used capacitors many times. They are a standard component along with the resistor whose values are lifted off the ...

There is a general trend of making electronics smaller and with more functionality. This translates into: “Cram it in there,” so naturally designers look to find smaller and smaller parts. What was on ...

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 ...

Film capacitors are passive components that use an extremely thin plastic film as a dielectric insulator. They are constructed of two pieces of plastic film wound into a cylindrical shape. The winding ...

Although not all applications are safety critical or mission critical, reliability is still a vital consideration for many electronic products. Making informed choices at the component selection stage ...

Tantalum capacitors are constructed using tantalum for at least the anode material. Capacitors in general consist of two polarized conductors separated by an insulating dielectric material. When the ...
