New edition edit

The actual existing article “Types of capacitor” contains a lot of discrepancies, f. e.

Under the sub-header “Types of dielectric” a lot of different things are mixed. It contains

  • general dielectric materials like: Air-gap, Ceramic, Glass, Paper, Vacuum,
  • detailed dielectric materials like: C0G, NP0, X7R, X8R, Polycarbonate, Polyester, Polystyrene, Polypropylene, PTFE or Teflon
  • capacitor types like: Electrolytic capacitors, Polymer capacitors, Trimmer, Double-layer capacitors,
  • “home-made” capacitors like: Gimmick, Printed circuit board,
  • very special customized types like: integrated circuits,

The sequence of the capacitor types in the table “Fixed capacitor comparisons” are not methodic, f. e. Paper, Metallized paper and Alternating current oil-filled capacitors as well as Direct current oil-filled and Kraft capacitor paper belong together. Additional capacitor types and application capacitor names are mixed.

Especially the comments to paper capacitors sounds like written in the 1950th and are old fashioned and partly obsolete.

Under the sub-header “Non-ideal properties of practical capacitors” some properties are described, which are standardized and in datasheets specified as “rated values”.

In the new edition of this article I have tried to follow strictly the industrial and the standardized view of the most important industrial produced capacitors. Greetings --Elcap (talk) 09:15, 13 December 2012 (UTC)Reply
