About CHK Elektronik
CHK Elektronik GmbH, based in Diepenau (Lower Saxony), develops, manufactures and tests inductive components such as coils, chokes, transformers as well as power supply and transducer solutions. The components are manufactured to customer drawings and specifications, with parameters such as power, current, voltage, inductance and frequency individually tailored. In addition to manufacturing inductive components, the company offers complete assembly production: component procurement, ESD-compliant electronics assembly, mechanical assembly, functional testing, labeling, packaging and shipping, up to warehousing on demand. Every component is 100 % unit-tested in accordance with the applicable VDE and EU standards; test results are documented and can be supplied. Typical industries include e-mobility, firefighting technology, swimming pool lighting, mechanical engineering, signal transmission, contactless charging, drive technology and plant engineering. Production takes place at the main plant in Diepenau as well as at fixed production partners in Poland and Slovakia; production runs from as little as 1 unit up to series of around 50,000 units per year.
