This tutorial explains how ceramic capacitor type designations, such as X7R and Y5V, imply nothing about voltage coefficients. Engineers must check the data to know, really know, how a specific ...

How do those defibrillators you see on TV actually work? Surprise! Physics can explain! So, how do those defibrillators you see on TV actually work? Surprise! Physics can explain! Okay buckle up, ...

Many single-phase motors used on refrigeration systems will incorporate some type of capacitor. They will either use a start capacitor to aid in its starting or a run capacitor to improve its running ...

Guest columnist Dale Cigoy, lead applications engineer at Keithley Instruments, outlines how an understanding of the challenges for testing capacitors can be invaluable to engineers. Capacitors are ...

Over the last 40 years, a series of misconceptions regarding mica capacitor applications has led novice users to consistently over-derate wound or rolled mica/epoxy dielectric capacitors. The mined ...

A few years ago, after more than 25 years of working with these things, I learned something new about ceramic capacitors. I was working on an LED light-bulb driver and the time constant of an RC ...

Medium- and high-voltage capacitors find widespread use as snubbers or filters in applications, such as switching power supplies for audiovisual and business equipment (computers, modems and fax ...
