Dear Support, I need to be sure that I choose the right product to repair!
The Market product says
EPCOS - C104 - 4390 - 43 (see drawing)
Is this the EPCOS B82789C0104H002. ? Please help me out !
Hello @hans1
Welcome to the TechForum
Yes, those would be the correct part markings for part number B82789C0104H002 as it states in the datasheet,
Marking on component:
Manufacturer, bifilar or sector winding (coded),
L value (in nH; for version B82789C0/S0*H052 underlined),
date of manufacture (YWWD), two last digits of production order
I have also included links to the datasheet and a general guide to the inductors which explain the part markings
