    What is your expected application?  How will connections be made between devices / boards / systems? 

    Could you clarify your question on HBM ESD?  Are you asking for clarification on the HBM ESD specification for the TLK110?

    Hello, thank you for your prompt reply.

    With regard to Seishin's inquiry, please let me add some detailed requirements from customer.

    Firstly, some pulse trans supplier for 100BASE-TX specifies its isolation voltage as 1500Vrms/0.5mA/2Sec.

    Please refer to the datasheet on the web site below;

    http://www.kowa-denshi.com/product/standard/pdf/12F-1X%20Series%20PDF%20Catalogue.pdf

    When considering to replace from trans into capacitor for isolation, which is described on Seishin's post, we need to take into consideration about the requirement for isolation voltage on capacitor, which seems to be same as isolation voltage on trans.

    Please let us clarify how to consider about this case.

    We thank you once again for your information.

    Best regards,
