KOA

Das Tochterunternehmen KOA Europe GmbH wurde im Jahr 1995 in Deutschland gegründet. Das Mutterunternehmen wurde bereits im Jahr 1940 in Japan gegründet unter dem Namen KOA Kogyo.

KOA Entwickelt und Produziert seine elektronischen Bauelemente in weltweit 23 Fabriken. Davon befinden sich allein in Japan 18 Produktionsstätten und die restlichen in China, Malaysia und Taiwan.

Das Produktportfolio umfasst Sämtliche Widerstände wie z.B. Dickschickt-, Dünnschichtwiderstände oder Shunts. Einen kleineren Bereich nehmen im Hause KOA die Sicherungen, Sensoren und Induktivitäten sowie Varistoren und LTCC ein.

Seit dem 1945, zertifiziert sich die KOA-Gruppe mit den sogenannten ISO-Zertifikaten. Unter anderem ISO9001, ISO14001 und heute die IATF16949.

Unsere beiden Häuser KOA Europe und Beck haben eine geschäftliche Verbindung seit 2001.
