GROUNDED: EMC/EMI & PCB Design Nuggets

Knowing the difference between differential-mode and common-mode currents is key to mastering radiated emissions and passing EMC certification quickly.

Why? They propagate differently and require distinct handling methods.

The critical point is understanding their root causes.

What drives these phenomena?

Can I control them during PCB and system design?

Are these emission sources predictable and manageable?

Yes, they are, with one caveat: you must know where to find them.

Once identified, diagnosing and fixing their issues becomes much simpler.
