PET-Folienkondensatoren

Der Preis-Leistungssieger

Polyester(PET)-Folien-Kondensatoren verwenden Polyethylenterephtalat-Kunstoff als dielektrisches Material und sind kostengünstiger als vergleichbare Folien-Kondensatoren. Allerdings ist ihre Temperaturfestigkeit geringer als bei anderen Folien-Kondensatoren. Ebenso verhält es sich mit der Frequenzabhängigkeit der Kapazität und des Verlustfaktors. Auch hier ist die Änderung im Frequenzbereich relativ hoch. 

PET-Folien-Kondensatoren sind besonders preissensitiv und können mit ihren Eigenschaften in vielen Bereichen der Schaltungstechnik verwendet werden.
