ADUM5000ARWZ EMI issue

Fuzihara-san:

In the past I have heard of applications using a metal shielded enclosure but not specifically using a ferrite sheet.  The new ADuM5020 can be used and does not need shielding or stitching capacitance to achieve CISPR22 Class B emissions.

Hi Brian,

Customer already designed a product using ADUm5000 so I´m trying to workaround without a completely new design.

Some improvements are easy such improving ground connection and changing capacitor position. But last shot would be shielding. In this scenario new component versus shield justify the effort.

Anyway thanks for feedback.
