Hi
I am using the DC-DC MURATA UEI30
input voltage is 24V and max current is 1.5A
need a recommendation for input filter in order to reduce conducted and radiated emissions

Shaffner filters mains and other ?
 

Thank you for replay but it seem I need to explain it better
I have AC filter and then AC/DC (first isolation) and then DC/DC (second isolation) (it is a medical system so we need double isolation)
Now, I am searching for the filter between the AC/DC and DC/DC
I know it should be something like a capacitor + Common mode + capacitor and then maybe one more inductor
And I see too many values of capacitors and common chocks and I am confused…
