Q.
Are there any restrictions for wire wound type common mode filters / chokes when a gold foil pattern is used on the circuit board to which they are mounted?

A. If the connection part of the wire is on the side of the circuit board, disconnection due to "solder erosion" may occur.
If the connection part is on the opposite side of the circuit board, there is likely almost no risk caused by "solder erosion."
