For impedance transformation/isolation applications when max power is < 10 Watts PEP, this transformer provides a simple interface between transmission lines with different connectors or impedances or simply common mode isolation. DC continuity for bias-T applications.

Excellent for large cables or multiple cables – use multiple cores for higher choking. Also useful when you need high turns count for high choking with large cable - works on large gauge DC power cables.
Note: put both positive and negative cables TOGETHER through the filter so that their differential currents cancel but their common mode currents are suppressed.
