Core Material used in DER-717 15 W Adapter using InnoSwitch3-CE with ±30 kV ESD Capability

Posted by: powerlion on

Could you please clarify what core material was used for this design? The core shape is clear but I couldn't see a part number for the core.

Thanks!

The web site I showed you in the first post was for the bobbin manufacturer. We at PI actually procure the cores from A-Core Jiagmen Electronic, CO, LTD in China

We are using their JPP 95 material

Thanks for the update, core material i.e. "JPP 95" is what I was looking for.
