Awhile ago, my subwoofer just stopped working (actually, if you turn it on, it just makes a loud buzzing noise). I tried getting it open but all the screws are messed up and i've since left it ...

Vintage equipment relies on many components to run properly, Chuck Gloman writes. Let’s focus today on what capacitors do in ...

New Bedford, Mass. — Cornell Dubilier's three new ElectroFilm series of power film capacitors may replace aluminum electrolytic capacitors in applications where increased reliability is required.

With their low equivalent series resistance (ESR), which allows for good ripple-current handling as well as high surge-voltage ratings and self-healing properties, film capacitors are strong ...

Part of the company's ElectroFilm Series, the UNL, UPP, and UPE power film capacitors offer a typical ESR from 5.0 to 14.0 mW and a current-ripple capability from 13.8 to 39.2 A rms at ...
