Certifications & Standards for Custom Inductors

Certifications & standards

Coils, also known as inductors, are passive electronic components that store magnetic energy in a magnetic field when an electric current flows through them. They are often used in electrical and electronic circuits to filter and limit currents or in resonant circuits for frequency selection.

Tailor-made inductors with tested quality and conformity to standards

Our customized inductors combine voltage adjustment, filtering and energy storage with clearly defined safety and efficiency requirements. We attach great importance to ensuring that all products not only meet the electrical characteristics, but also pass international standards and tests. These include insulation tests up to 6 kV, EMC tests with interference suppression above 60 dB and thermal stress tests.

We support purchasers with traceability and complete specification documents, while engineers benefit from simple integration into complex systems. Whether in medical technology, energy supply or industrial automation, our solutions are versatile. The variety of designs - from toroidal core and PCB variants to multilayer windings - allows precise adaptation to the respective application.

By using materials tested in accordance with UL 94 V-0, EN 60601 or IEC 60076, we achieve consistently high quality and international approvals. This ensures that every customer-specific inductor is a reliable and durable element of your technology.

Customized winding technology for efficiency and EMC-compliant design

In our developments, we focus on maximum energy efficiency and a consistently EMC-compliant design. Whether it's suppressing high-frequency interference in drives, smoothing in DC/DC converters or galvanic isolation in control circuits - our solutions are always adapted to the specific project.

We manufacture inductors with values ranging from a few microhenries to several millihenries and currents of up to 500 amperes. Transformers from our production cover voltage ranges from 10 VA to over 50 kVA. For engineers, this means the availability of solutions with low leakage losses, optimized heat dissipation and robust insulation. Buyers can rely on calculable costs, predictable delivery times and individual advice.

Thanks to modern winding technology, the use of high-quality materials and stringent quality tests, we create inductors that are durable and reliable. At the same time, we ensure compliance with international standards and EMC directives so that you can implement systems with maximum efficiency and operational reliability.
