Hello, I've got a 701c's boards with some missing components. Could someone help me to find out the nominals of the following components. As I understood, these are common mode choke filters. I have found a similar component in China named ACM3225, but there are different types which have different impedance at 100 Mhz. I don't understand how to choose the right one.
