Suggested schematic for EN55022 conducted emission Class B limits
Recommended Layout With Input Filter
To meet conducted emissions EN55022 CLASS B needed the following components：
TEP 75-72xxWI
Component Value Voltage Reference
C1, C2 150 μF 200 V Nippon chemi-con KXJ series
C5, C6, C7, C8 1 μF 250 V 1812 MLCC
C9, C10, C11, C12, C13, C14 1000 pF 3 KV 1808 MLCC
L1 1186μH ± 35% ---- Common Choke,
P/N：PMT-064
L2 4.7 μH ± 20% ---- Inductor, P/N: TCK-099
Note：1. Common mode choke and inductor have been dened and show in page 54.
2. While testing, connect the CASE pin and four screw bolts to shield plane, the EMI could be reduced.
