Component parameter:BK1080 > Parameter of FB1 (value)?

Unfortunately I cannot view the picture you uploaded.

The value of FB1 is non critical in my opinion. That's why I didn't measure its exact values. It is used to block stray RF from entering the BK1080 power line.

Candidates could be something similar to Coilcraft's DF series (https://www.coilcraft.com/de-de/products/rf/ferrite-core-chip-inductors/0402-(1005)/0402df/0402df-221/).

When I have time during the next weeks, I can try to measure its inductance.

Thank you for the response
