NOTE:
The “High Frequency” 4-wire common mode chokes provide an effective means of compliance with national and international regulations on
EMI. They are designed to be used in conjunction with Pulse's ISDN S-Interface transformers. A high inductance “Low Frequency” common mode
choke is recommended to improve balance or to correct inherent unbalances of some ISDN S-Interface circuits.
