Abstract

1460183 Capacitors MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 21 June 1974 27760/74 Heading H1M A capacitor is wound from unmetallized polypropylene film 2 and polyethylene terephthalate film 1 metallized on both sides, e.g. by vapour deposition. Polypropylene has the better dielectric properties, whereas polyethylene terephthalate is less affected by heat during the metal deposition and application of metal contact layers to the roll end faces. Preferably the width of the polypropylene film is slightly less than that of the polyethylene terephthalate film and its thickness 70 to 90% thereof.
