Indicatively.
RF line have output amplitude 50V ,output current 3A
Inductor separating the DC circuits that injects DC current into RF line (it is used for detecting if Load is connected).
If to injecting DC current use 3x coil 47uH with 10nF capacitor for canceling AC current. Current from RF line over 3x 47uH will be 3mA i.e 100mW power dissipation on three inductor. Originally, I counted max 70mW, but on PCB is not space for more inductor.
Farenell offer 68uH 1812 inductor COILCRAFT
1812LS-683XJLC, but price is 2$/pcs and this is a bit pricey.

Still I do not understand one thing.
Farnell offer
TDK NLFV25T-680K-EF
68uH Self Resonant Frequency 10MHz , but in
datasheet
on page 7 L FREQUENCY CHARACTERISTICS GRAPH I see 68uH have peak of L on 14MHz 200uH. and on page 9 IMPEDANCE FREQUENCY CHARACTERISTICS GRAPH 68uH have peak of impedance on 15MHz over 25k Ohm.
How am I supposed to understand that?
If I used two pieces should not be a problem.
Power disipation, 1008 size is bigger than 0805 resistor and 0805 have power rating 125mW
