FILTER CHOKE

Good evening,

For one of our project choke is required. we used 24 SWG for making the choke. The resistance of the copper wire is 84 Ohms per Km,
The resistance of cooper wire for 1 meter is 0.084 Ohms. For 8 turns the length of the wire is 62 Cms  is < 60m Ohms. for 8 strands the resistance 6m Ohms. Otherwise the Voltage drop is HIGH when the current is around 20A.
Here we need the voltage drop is below 0.2 Volts.
The choke is implemented in the 40mm core as shown below.
