I have a 220 V 50 VA to 2* 12 V 2.1 A transformer followed by KBL10 (1 kV, 4 A) Graetz bridge rectifier. After rectifier, I get around 10 V of AC, which I'd like to eliminate. After doing some research in the Internet, I'm thinking about using a choke to block the AC part of the voltage.
I'm thinking right now about using Radiohm 42H22 30 00 or 42V25 30 00 chokes (3 A, 1.2 mH, 70 mΩ per winding). Would they be good enough for my use? If not, what inductance should I use, or even better, how would I calculate needed inductance? I'm pretty new to that field.
