... Common Mode Chokes The “high-frequency” 4-line common mode chokes, in the chart below, provide an effective means of compliance with national and interna- tional regulations on EMI. They are designed to be used in conjunction with Pulse’s T1/CEPT transformers. Crosstalk is typically – MHz and – MHz. ...
