Custom magnetic components manufacturer

Custom Common-mode chokes

A common-mode choke belongs in the system's noise-control path, so its useful specification starts with the lines, current conditions and interference problem.

Where it fits

What to include in your choke RFQ

Start here when conducted or common-mode noise is affecting a power or signal path and the component has to fit a defined harness or board layout.

Useful inputs for an initial discussion

Line count, wiring and current conditions
Frequency range and attenuation target
Differential-mode considerations
Dimensions, terminals and mounting
Temperature, hipot and other applicable tests

Next step

Start with a drawing or reference part.

Share what you already know and label the open points. A drawing, reference part, electrical targets or a short application note can all be useful starts.

Final suitability, samples, documentation and pricing follow review of the project specification.

How to evaluate a custom magnetics supplier ↗

What should I send for a custom common-mode choke quotation?

Include the number of lines, wiring arrangement, current conditions, relevant noise-frequency range and attenuation target. Add dimensions, terminals, mounting, temperature limits and applicable insulation or test requirements.

Can I enquire about flat-wire or three-phase common-mode chokes?

Yes. The PV and energy-storage portfolio includes flat-wire and three-phase common-mode choke examples, and the automotive portfolio includes EV charger three-phase examples. Send the line arrangement and operating requirements for a project-specific review.

Do I need to describe the surrounding EMI filter?

Include the circuit or filter context when available, together with the noise measurement conditions and the component constraints. A part number or an inductance target alone may leave important requirements undefined.
