Prototyping wire
« on: January 10, 2020, 04:14:51 pm »
Hi,
I use this wire for prototyping:

906858-0

It is 0.3 mm diamater solid tinned copper wire, overall diameter 0.7 mm, silicone insulation (so it can withstand high temperature during soldering).

I'm running out of this cable. Do you have any idea where this can be bought?

Are you sure it's silicone insulated?  It looks like regular 30AWG Kynar insulated wire wrap wire.  Kynar is kind of hard and waxy, rather than soft like silicone.  It's a lot easier to strip.

P.S. If you want tips on where to buy things, you shouldn't set your country to 00.

This vendor sells 26AWG (0.4mm diameter) solid wire with silicone insulation. But I’m sure its overall diameter is much larger than 0.7mm (they don’t specify).

With that said, I agree with edavid that your wire is unlikely to be silicone. Silicone insulation is comparatively weak, so it tends to be thicker than PVC insulation, which in turn is thicker than Kynar (PVDF), Tefzel (EPFE) or Teflon (PTFE) insulation, since those materials are tougher. Alas, those materials are also a lot more expensive, making such wire rather costly. Best bet for those is to get them from military surplus. (I need to go back to Los Angeles so I can go to Apex, which sells such wire by the pound!)

You are right, it is probably not silicone, it is not soft. But definitely it is high temperature resistant, it does not burn when I touch it with my solder at 350 °C.

I'm from central Europe, Czech Republic. Not sure why there is 00 as my location - in my profile here I have location filled with my country.

It is very probably teflon coated wire. That is very common for prototyping.
There are small lies, big lies and then there is what is on the screen of your oscilloscope.
