1. Produkteinführung des CDRRI-Induktors
Produktionsdetails: Der CDRRI-Induktor ist eine Verbesserung der Grundfunktionen von I-förmigen Induktoren. Um die Drähte, Schleifen und Spulen vor dem äußeren Magnetfeld zu schützen und die Störwirkung des vom Stromkreis erzeugten elektromagnetischen Feldes auf andere Komponenten abzuschwächen, werden magnetische Materialien verwendet. Ein Induktivitätsmodus zur Abschirmung, dessen Hauptfunktion darin besteht, die Störungen der Induktivität nach außen zu reduzieren.
