Sometimes when you need a component, the best way to get it is by building it yourself. [North Carolina Prepper] did just that, creating his own trombone-style variable capacitor by stretching some ...

Bypass capacitors are found in every working piece of electronic equipment. Most engineers know that systems, circuits, and individual chips need to be bypassed. The methods for choosing bypass ...

When choosing a capacitor for any application, there are a few key characteristics that must be understood in order to analyze its suitability for the circuit. In a simple capacitor equivalent circuit ...

This file type includes high resolution graphics and schematics. Capacitors often are connected in parallel in power electronics to decrease high-frequency ripples, current stress, decrease power ...

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 ...

Many power supplies use hold-up capacitors to keep enough energy at the full-wave or bridge rectifier output to supply a load when the rectified voltage drops and rises again at the next half-cycle of ...

Your phone died. Again. In these scenarios, who among us has not dreamed the dream of a future where our devices charge instantly and last forever. As capacitors—or even more exciting, ultracapacitors ...
