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 ...

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 ...

Ceramic capacitors are small, they don’t leak, they’re convenient, but they are downright strange. Certain types of caps will lose their capacitance depending on the voltage they’re operating at. If ...

Vishay has introduced 1, 2 and 3kV multi-layer ceramic capacitors for commercial applications. In seven case sizes from 1206 to 2225, they are made with either C0G (NP0) or X7R dielectric. C0G types ...

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 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 ...
