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 ...

Devices that plug into an AC mains outlet need protection from EMI. A Pi filter, as shown in Figure 1, is often used for this application. Safety standards exist to protect people and equipment should ...

The pioneering years in the history of capacitors was a time when capacitors were used primarily for gaining an early understanding of electricity, predating the discovery even of the electron. It was ...

The four basic capacitor types. The key parameters involved in selecting the right capacitor for automotive designs. Advantages and limitations of electrolytic and electrostatic capacitors. Choosing a ...

A snubber circuit limits voltage spikes in power converters. Snubbers are also used in the output of Class-D audio amplifiers for the same reasons (Fig. 1). When the transistor you use to switch the ...
