About KOA Europe

KOA Europe GmbH is the European headquarters of the Japanese component manufacturer KOA Corporation, located in Dägeling near Itzehoe (Schleswig-Holstein). The company distributes passive electronic components, including SMD and leaded resistors, current-sense shunt resistors, thermistors and thermal sensors, fuses, varistors and shunt current sensors. The portfolio includes, among others, high-precision thick-film and thin-film chip resistors (e.g. RS73, WN73H), anti-pulse-proof series for automotive (SG73P, HSG73P) and multilayer metal-oxide varistors (NV73S) with peak currents up to 6000 A. Many products are AEC-Q200 qualified and EU-RoHS compliant and are aimed at applications in automotive, industrial electronics, medical technology, measurement and test engineering, and power supplies. In addition to distribution, KOA Europe offers technical support, parametric product search, cross-referencing and Lab Kits. Customer awards such as the Rutronik A-Supplier Award (2025) and several TTI Awards (2024) confirm its position as a supplier for distributors.
