I need to tether a TO-92 package IC to a PCB - as shown in figure below. The cable length would be less than 50mm. Conceptual figure

Questions:

  1. How can I achieve CONN1 - i.e, attaching a cable (comprising of at least 3 wires, for the 3 pins of the TO-92 IC) to the PCB.
  2. How can I achieve CONN2 - i.e., attaching the cable to the TO-92 IC when the IC is not on any firm surface.

  • \$\begingroup\$ I would find it tricky to solder the 3 wires directly to the TO-92 IC pins (for CONN2). Would you use any particular kind of wire in such a situation? \$\endgroup\$

  • \$\begingroup\$ Is this for a DS1820? You can buy them with a metal cap and wires attached, neatly crimped an all. Add a CONN1 to your taste and your are done? \$\endgroup\$

Use a 3-pin header cable:

with the header plug on both sides. The TO-92 will plug neatly into that. I´m not sure exactly how you can then fix it all off-board, but that shouldn´t be too difficult.
