Common Mode Currents Are Sabotaging Your PCB Design
You’ve nailed your circuit design.
Or so that's what the lighting LEDs let you believe.
Your device is doing everything you hoped it would, until EMI testing hits you like a freight train.
That perfect prototype is now spewing noise into the ether, and compliance testing is laughing in your face.
Here's the thing: If your cables or traces are radiating like FM towers, common mode currents are likely to blame.
And the worst part?
They’re sneaky.
You might think you’ve handled them, only to find out during testing that they’ve slipped through.
Here’s where most engineers miss the mark: they treat EMI as a “later” problem.
But solving for common mode currents upfront saves you time, money, and headaches.
