Where to get some board-edge BNC jacks/part number?

Looking for those board-edge jacks e.g. Mr. Larkin uses with the two
solder-lugs that can be grounded to the plane. Part number at
Mouser/Newark would be great if you got it.

The Vbites?

MFR1 BOMAR CON 361V509E
MFR2 ALLIED 202-0450
MFR3 MOUSER 678-361V509E
MFR4 NEWARK 80K0248

One thing to be careful about is the PCB thickness. Go for 64 mils
max. Deleting the solder mask in the mating area can buy a couple of
mils.

Those are nice, but I had more in mind the type I see you use on
copper-clad manhattan-style protos, that have the two lugs coming out
parallel to the connector barrel and then solder-blob those to the board.

Maye they aren't BNC I can't recall what the end termination was, now...

Looks like they've gone away completely--apparently no one has any stock. :(

We use these ones
CON COAX BNC JACK 50OHM BULKHD PCB THRU 13-60-3 DGZ
Multicomp $1.41 Newark

CON COAX BNC JACK LOPROF BULKHD PCB THRU 5413879-1 Tyco AMP
$4.50

They're die-cast zinc things, which survive the stomp test (ripping an
RG-58 patch cord out by stomping on it) but aren't super good for high
frequencies on account of the lead inductance.

Try Amazon or ebay. They have all sorts of cool connectors.

Amazon has lots of edge-launch SMAs, crazy cheap.

I use edge-launch SMBs for slower stuff. They push on, much easier to
work with than the threaded SMAs.

I've tried buying some real cheap SMAs you could melt the isolation. it is supposed to be PTFE so that shouldn't be possible

All Amazon shipments of "non-essentials" are delayed for me, I don't
think they consider connectors "essential."

As of last night shortest Prime shipping-time on stuff like that to my
location, usually two-day, was about a week, some stuff I usually get
there too like SOIC "surfboards" they're estimating a month. :(

I managed to get my hands on some of these from the local
brick-and-mortar parts store which is thankfully (reasonably!)
considered "essential" and still doing curbside pick-up from the loading
dock. It'll have to do for now:

BNCs aren't as good as (otherwise identical) TNCs because above 1GHz,
they leak around the slots. I forget where I saw the paper that
investigated this effect, but I thought it was interesting.

No, never use them. I recall extreme insertion and removal detent

I'd use them in particle accelerators. Radiation does bad things
to teflon. Polyethylene and polystyrene fare much better.

Hi Jeroen,

I just bought 40 of these, for EUR 0.15 a piece, the cheapest I could
find in that shape, for use at 868MHz. I just tested one: it does not
melt at 380C. I think you will have a hard time finding non-PTFE versions...

Thanks. Indeed, teflon is a great material in almost all
cases. Low loss, high melting point, just the right mechanical
properties. Alas, only about 1kGy of radiation is enough to
turn it into a hard brittle acidic lump that attacks all metal
surfaces in its vicinity. Even gold gets tarnished. Connectors
become unreliable very quickly.
