IMX35 Series Data Sheet
35 Watt Quad-Output DC-DC Converters
Conducted emission according to EN 55011/55022, class A,
can be achieved by adding an external common mode choke
and an additional ceramic capacitor. The filter components
should be placed as close as possible to the input of the
converter; see figure 15.
