Could you please kindly recommend the type of ceramic disc safety capacitor to
mitigate EMI? There are various type of ceramic disc safety capacitor, for
e.g., X1, X2, Y1, Y2.
I would appreciate if you could recommend a general one which can be used in
this case.

 

For recommendations on ADuM5402 EMI mitigation layout, please refer to the
attached layout. We have been using 100pF ceramic safety caps from Murata. 
These caps have a resonance near 300MHz.  We are working with Murata part 
DE1B3KX101KA5B components right now, it should be a good starting place..
