Engineers need to fit components into small power supplies. These capacitors help make electronics smaller while keeping ...

Radio experimenters often need a variable capacitor to tune their circuits, as the saying goes, for maximum smoke. In decades past these were readily available from almost any scrap radio, but the ...

Lightweight, small-size, and high-power-density power converter systems, which use only switches and capacitors in their power stage, have no need for transformers or inductors in their design. This ...

As engineering innovations continue to advance ultracapacitors, their enhanced performance capabilities are expected to hasten the convergence of batteries and ultracapacitors—strengthening the ...

A printed circuit board turns separate parts into a stable system that powers up, talks to peripherals, and survives real ...

Scientists are working to create electronics capabilities for electric vehicles, with the development of a high temperature capacitor. Scientists at the National Physical Laboratory are helping to ...

Single-phase motors, adjustable-speed drives (ASDs), and power factor (PF) correction applications often depend on capacitors to operate properly. This article explains how to test these critical ...

As things stand, the internal combustion engine looks like a doomed device. The UK government has put plans in place to ban the sale of new petrol and diesel cars by the year 2030, and those plans are ...

The rules of the National Electrical Code are written for people who have a pre-existing knowledge of electricity. In order to make sense of the Code, you must first understand basic electrical ...

Kemet has launched the R41T and R76H series AEC-Q200 qualified metallized polypropylene film capacitors. The series is aimed at automotive applications, including those for electric vehicle (EV) ...
