Choosing the best wirebound inductor for an ampilifier

[John.Jin1990]

Hello,
I need to know the best RF inductor (wirebound) for my AVA-183+ amplifier. I have seen this inductor(0603CS-3N3XJLW) it is a high Q inductor, would it be a good selection? I need to find the best inductor for my application and I will be grateful if you could help me.

0603CS-3N3XJLW from Coilcraft is a good choice for this application.

Hi,

"Best" regarding "what"?
Price, color, size, solderability, highest current, lowest DC loss, lowest AC loss, lowest distortion, widest frequency range
There are many more "best" qualities...

Indeed. Color is on the second place of importance choosing an inductor...

If you're following minicircuit's recommended application circuit, then I guess you're talking about L1 which is just used as a DC supply choke. It's highly unlikely that the Q of that inductor is going to affect performance noticeably (assuming you're following the rest of the the circuit faithfully, that is).

Minicircuits mentioned in the datasheet to use a wire wound 0805 3nH inductor.
At this relative low inductance and relative high SMD dimension, I think all the wire wound inductors are high-Q.
Even a cheap 3nH Murata inductor has Q>80.
