But any ways i will be excited to have some calcuation model in terms of selection depending on inductances. Regards, Ahmed

Alternatively, you could evaluate if the DC factor is truly a concern or a false positive. If it's a legitimate issue, then proper grounding and shielding are crucial. Only if these measures are insufficient should you consider more complex solutions like chokes or power factor correction... Regards, Pankaj Tiwari
