K2 RF Board RFC15

jperelst
I think that I received a full-sized 100 microH RF choke instead of a miniature.
 
I have four green-bodied brown-black-brown RF chokes and a tan-bodied brown-black-brown RF choke -- all the same physical size.  Actually, I'm can't tell for sure if the tan-bodied is a brown-black-brown or an orange-black-brown, but I think it's brown-black-brown (sorry, the color strip is just not distinct enough for me to tell).
 
Can I use a full-sized choke for RFC15, or do I truly need a miniature?

Use the one you received. The miniature choke was too easily damaged and
is no longer supplied.

Jon,

Actually, those are all miniature chokes.  Use any one of them at RFC15,
but if you have one that is different looking, I would suggest using
that one at RFC15.

I bend one lead back along the body of the choke,  and I solder the
unbent lead to pin 16.  That keeps the exposed lead further away from
tinned solder pads and via holes on the board.  There is no right or
wrong way to orient it, that is just the way I do it.

After you install it, check the resistance across it with an ohmmeter to
be certain it did not become open during the lead bending and soldering
process.
