Variable capacitors may be useful, but the air gap that provides their capacitance is their greatest weakness. Rather than ...

Every now and then you need to make your own capacitor. That includes choosing a dielectric for it, the insulating material that goes between the plates. One dielectric material that I use a lot is ...

Electronic circuits are integral parts of nearly all the technological advances being made in our lives today. Television, radio, phones and computers immediately come to mind, but electronics are ...

AVX Corp. has developed a new Niobium Oxide Multi-anode (NOM) capacitor, designed to deliver low ESR, high capacitance, high-ripple current capacitor performance. Designated the OxiCap Series, this ...

Experimental electrical double-layer capacitances of porous carbon electrodes fall below ideal values, thus limiting the practical energy densities of carbon-based electrical double-layer capacitors.

One common trend in switch-mode power supplies, microprocessors and digital circuit applications is the reduction of noise while operating at higher frequencies. In order to make these possible ...

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 ...
