20 Watt | DC-DC Converter
Note A:
Input filter components (C1, L , see circuit below) are used to help meet conducted emissions requirement for the module.
These components should be mounted as close as possible to the module; and all leads should be minimized to decrease radiated noise
.
Series AM20E-Z
Note B:
An external filter capacitor is required if the module has to meet EN61000-4-4 and EN61000-4-5.
The filter capacitor suggested value of 220uF/100V.
