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 ...

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 ...

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 ...

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 ...

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 ...

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, ...

Single-phase motors, adjustable-speed drives (ASDs), and power factor (PF) correction applications often depend on capacitors to operate properly. This article explains how to test these critical ...

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 ...

Dialog Semiconductor has announced a 10A switched-capacitor voltage divide-by-two, that operates at up to 98% efficiency, hitting or exceeding 95% at 10A. Called DA9313, it can deliver over 50W from ...
