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 ...

When Ceramic Capacitors Go Bad – Aging. Capacitor Aging applies to all Class 2 ceramic capacitors as they are built of ferroelectric materials. C0G types (Class 1) do not exhibit this aging effect, ...

Within the body of a high-voltage multi-layer ceramic capacitor, a gap-type defect is beginning its career of destruction. The defect may be a void within the ceramic dielectric, a crack within the ...

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 ...
