Applications
For low-interference power electronics
Common-mode chokes are used wherever high-frequency interference must be reliably limited and EMC requirements must be met.
Mains and EMC Filters
Reduction of conducted common-mode interference at the input or output of electrical devices.
Power Supplies
Filtering in switching power supplies, power supplies, and DC systems.
Power Supplies
Interference suppression on the mains, DC link, or motor side of power electronic drives.
Charging Infrastructure
Magnetic filter components for chargers, on-board chargers, and other electric vehicle applications.
Renewable Energy
Filtering in inverters, energy storage systems, and power conversion systems.
Industrial Automation
Rugged EMC solutions for control systems, machines, and networked industrial facilities.
Interpretation
Magnetics Tailored to Your Application
Effective filtering depends on the entire system. That is why, during the design phase, we take into account not only inductance and rated current, but also the interference spectrum, DC resistance, parasitic capacitances, insulation requirements, temperature, and available installation space. The core material, winding configuration, and terminal configuration are selected to match the operating point.
Electrical: Inductance, Current, Frequency Range, and Losses
Thermal: Ambient Temperature, Self-Heating, and Cooling
Mechanical: Installation Space, Mounting, and Connection Technology
System-level: Number of phases, topology, and EMC objectives
Please send us your requirements
A circuit diagram, load profile, interference spectrum, or existing data sheet is sufficient as a starting point. Our experts review the requirements and recommend a suitable standard model or develop a custom common-mode choke.
