please , I want the parts in the pcb because i did not find it in the parts , which is (KF250-3.5 )
- I have project that i need quickly
that is datasheet ( https://datasheet.lcsc.com/szlcsc/2001151504_Cixi-Kefa-Elec-KF250-3-5-12P-1_C475162.pdf )
how many pins i need ?? 3pin and 8pin
It is unclear from the data sheet how this connects. For instance on a 3 pin connector are there 3 pins or 4 (the 4th pin being NC?) I assume it connects like this, but even that is unclear.
here I am assuming the 4th pin exists for stability (which it may not!) but is NC. I am also assuming there is a single connection for each wire. I would need to know what a 3 pin connector actually looks like to make a part.
From this picture of a 2 pin terminal it looks like unused pins are not populated so a 3 pin should have only three pins
with the 3rd pin being where the red dot is in the image above. Is that correct?
OK here is a part that should match a 3 pin terminal block. Please print out the footprint at 1:1 scale and compare it to a real part. If that looks correct I’ll make an 8 pin version.

Here is the 8pin version.
