Damping of EMI Filter

[iamakda]

Hi,

I have designed a differential mode filter by using MKT capacitors and now for damping of the filter what type of (Cd) capacitor should I use? Can I use electrolytic one or shall I go for MKT again or shall I use any other type of capacitor?

Thanks.

Re: Damping of EMI Filter

I will see if I can plug in the value of the parts and run the simulation without the damping to find out the peak/dip of the sweep frequency.
Do you have the value of the inductors and the caps/ What is the source impedance, 50 Ohm, 600 Ohms, the load impedance 50 Ohms, 600 Ohms?
What is the DC resistance of the Inductor?

I have all the values of inductors, capacitors, damping resistor and damping capacitor. The value of damping resistor is 0.1 ohm and damping capacitor as 250uF. The capacitors used in the main filters are MKT type. now I just need to know that type of capacitors I can use for damping capcitors ?

Thanks.
