Our Custom Design Studio

A customized experience

Steward of transformers - created with you - engineered by people who understand your needs

Our engineers develop transformers for you that are as individual as your application – precisely aligned with your technical requirements and a focus on your priorities: whether it’s a cost-optimized design, a high-efficiency transformer, or a focus on compact dimensions. Whether flyback, isolated buck, or push‑pull: we possess proven expertise across a wide range of common topologies. This allows you to finalize the layout of your PCB for DC/DC or AC/DC power supplies with a transformer specialist at your side – in every project phase.

Our core competence lies in custom magnetic solutions used in a wide variety of applications. Since each solution is as unique as the request itself, our capabilities cover a broad range - supported by a globally established team.

Our expertise for custom magnetics

At the beginning, we jointly evaluate your technical requirements and assess whether a component from our extended standard portfolio is suitable: Transformers for AC/DC ConverterTransformers for DC/DC ConverterGate Drive TransformersPFC ChokesCurrent Sense TransformersWireless Power TransmissionCommon Mode Chokes

Whether an optimization of one of our standard compoinents or an innovative application‑specific design is required - our proven cutting-edge Design for Manufacturing expertise provides the best foundation for your project.

Our engineering team integrates your electrical parameters, safety specifications, and mechanical requirements with precision into our highly automated manufacturing processes. By collaborating closely with you from the early stages of the project, we ensure a smooth transition from concept to series production - efficient, reliable, and cost‑optimized.

We act as a trusted partner at your side, turning your objectives into reality with technical precision and outstanding quality.
