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 ...

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 ...

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 ...

High-voltage Multi-Layer Ceramic Capacitors (MLCCs) are great for roles such as coupling, DC blocking, snubbing, or power-supply resonators. Their high volumetric efficiency delivers high capacitance ...

Kemet is aiming at fast-switching wide bandgap semiconductor (GaN or SiC) power supplies with high-voltage multi-chip ceramic capacitor assemblies. The parts, branded ‘KC-Link with Konnekt’, feature ...

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, ...

Penn State researchers have developed a new high-temperature polymer capacitor that can store four ...

I suppose a better question is, when is it not OK to use a higher voltage than original? I know with non-polarized capacitors for use in speaker crossovers, they say higher voltage caps simply allow ...

[Grenadier] tipped us off about his method for building your own high-voltage capacitors. He thought the paper and foil capacitor project was a nice introduction to the concepts, but at the same time ...
