NOTE: Common Mode Chokes for EMI reduction are also available. Recommended part numbers are either PE-68624 (surface mount) or PE-65944 (through hole) –
see data sheet G002. For North American applications when MLT circuit is utilized, DC current through the transformer is minimum. For these applications, smaller
size packages are available in both surface mount and through hole configurations. Contact Pulse Applications Engineering at (619) 674-8100 for more information.
