Vishay Intertechnology, Inc. introduced a new series of three-phase cylindrical capacitors for power electronics featuring high current capabilities, nine standard voltage ratings from 400 VAC to 1650 ...

Vishay’s 299 PHL-4TSI series of snap-in aluminum electrolytic capacitors includes a diverse selection of 350-V, 500-V, 550-V, and 600-V devices. Recent additions significantly broaden the ...

The ever-increasing trend toward miniaturization and flatness of electronic devices is a given for consumer markets, but now the demand for smaller power circuits has also spilled into industrial and ...

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 ...

Taiyo Yuden's new Cylindrical Lithium Ion Capacitor (LIC) offers extremely large energy capacitance and high reliability. Combining the strength of lithium-ion secondary batteries with conventional ...

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.

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 ...

Ferroelectrics are getting a serious re-examination, as chipmakers look for new options to maintain drive current. Ferroelectric materials can provide non-volatile memory, serving an important ...

The capacitance of a classical conductor is determined solely by its geometry. When charged, the electrons distribute in space in a manner that minimizes their electrostatic energy. Quantum mechanics ...
