KOA Widerstände
Thin / Thick Film / MELF / Jumper / Network / THT
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.
Die KOA-Gruppe verfügt seit 1945 über ein nach DIN EN ISO 9001 und DIN EN ISO14001 zertifiziertes Qualitätsmanagementsystem. Seit 2018 ist das Unternehmen noch nach dem neuen Standard IATF16949 zertifiziert. Unsere beiden Häuser KOA Europe und Beck haben eine geschäftliche Verbindung seit 2001.
