10. Inductor Basics
Question.2
Shantanu is designing an input EMI filter for a device powered by 12 V DC.
He chooses a standard wire-wound inductor (10 µH, 3 A) and places it in series with the input supply line to reduce noise.
However, he notices that common-mode noise is still high, and EMI test fails.
What is the most likely reason?
