Engineers designing power electronics find that capacitors are needed for several functions, from energy storage to filters and decoupling. Different capacitor types are available, that at first sight ...

You can work with a part for many decades, and still learn something new about it. At least we can, and we don’t mind admitting it. Take film capacitors — we all know they aren’t a polarized part like ...

Film capacitors are passive electronic components that store electrical energy in an electric field between two conductive ...

Today's engineer is faced with several options when selecting capacitors for use in high reliability switch-mode power supply (SMPS) applications. Each type has advantages and disadvantages that are ...

You should limit thermal dissipation to a maximum of 15°C above ambient, and at no time should it exceed the maximum temperature rating of the capacitor. Film capacitors have been rapidly evolving to ...

KEMET has announced the C4AK high temperature, power film DC-Link capacitor designed specifically for continuous operation up to 1,000 hours at 135℃. The C4AK series joins the C4AU (harsh environment) ...

Yi Liu (left) and Zongliang Xie fabricate film capacitors from polymers and then evaluate both the polymers and capacitors at the Molecular Foundry. The Department of Energy’s Lawrence Berkeley ...

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 ...

The choice of dielectric material significantly influences the performance of film capacitors in high-frequency applications, impacting energy storage density, dielectric strength, and overall ...

(Nanowerk News) Lawrence Berkeley National Laboratory (Berkeley Lab) and several collaborating institutions have successfully demonstrated a machine-learning technique to accelerate discovery of ...
