Hi,

Kindly clarify the query regarding the EE1621 bobbin used in DER-528.

In the BOM it is mentioned EE1621 8 pin Vertical(4+4), but in Winding Illustrations mentioned in section 7.6 looks like EE1621 10 pin(5+5) Vertical bobbin and 1 pin is pulled out symmetricaly. Can you confirm whether the EE1621 bobbin is 10 pin or 8 pin?

Appreciating your reply in this!!!

Gentle Reminder!

Hi,

I apologize for the late reply. The right part is 8-pin. The bobbin was sourced in China from a company named Shen Zhen Xin Yu Jia Tech.

I will let the one who made the DER know about the error to fix it.
