Interesting inductor

So I'm doing a new lab amp product.
Our existing one is 500 Hz -- 20 MHz, 1.1 nV/sqrt(Hz).
The new one is aiming to be 10 kHz -- 200 MHz, 0.25 nV/sqrt(Hz).  The spherical cows love it, so we'll see when the test boards arrive later this week.
As part of the design, I wanted to make an emitter follower with a decent amount of inductance in series with its tail resistor, to avoid the transistor turning off on fast negative edges and causing linearity problems.
Searching on Digikey, I found this very interesting part:
<https://www.digikey.com/en/products/detail/epcos-tdk-electronics/B82498F1472J000/697521>.
4.7 uH 0805 wirewound, with a self-resonant frequency of _210 MHz_, which is several times higher than many other parts of that description.    That corresponds to an effective parallel capacitance of 0.12 pF, about that of a resistor of the same size, despite all the copper windings.
Pretty nifty, if true.  (Parts on order.)
Cheers
