BYO cabling, "standard" 0.025" pin header plugs. They will take more than the 1A rated current.

Thanks for posting. The product in the photos at your link above looks good but the link at your link doesn't seem to go to the product and the product number doesn't seem to be findable. Maybe a double check? Thx

Or if you read that (short and concise) thread, a whole 2 posts along:
https://www.eevblog.com/forum/testgear/best-way-to-securely-attch-probe-to-a-passive-smd-component/msg1310906/#msg1310906
you get the OEMs part number.

Thanks! Looks like same part at a better price.

I ordered a pair of these. They are pretty small: about 2.5 cm long with the plastic housing and about 5mm wide on the jaws, so they are a good size for SMDs but they are a bit finicky to keep in place as you try to make measurements. If you have steady hands and your leads are long enough to reach your DUT they will hold, somewhat. You have to make your own leads. I had some female to female Dupont connectors about 6 cm long that attached to the male pin inside each jaw clip handle and then I extended those 60 cm with 22 gauge solid wire and then attached the wires to banana jacks. When it was all put together they read within about 0.1 milliohms of the TLDK1 Kelvins on my reference 45 cm copper wire. Unless you are really into low ohm SMD readings I'd say the TLDK1 leads and clips are a better use of the budget but it was an interesting look-see.

I bought it on eBay for a slightly higher price.

For those in Europe (or placing orders from USA, etc large enough to warrant the shipping cost), Reichelt.com has those for just over €10: https://www.reichelt.com/ch/de/miniatur-pruefclip-smd-bauteile-0-64-mm-schwarz-micro-smd-clip-p106195.html

That's a good deal even if you have to ship a couple from Europe to the U.S. At the reichelt price they make sense if you are doing SMD, and to be square they hold onto regular resistor and other wire leads ok too. Definitely not as much clamping force as conventional Kelvin clips but ok for taking a measurement.

I use these multicontact kelvin crocodile clips for the low resistance measurements. The cable is silicone-insulated coaxial. The measurement is far more stable than with the 4 wire+clip I used before.
