Hi team,

Could anyone let me know what's the 1 and 2 mark below?

I think 1 should be 0.25 and 2 be 0.5, just to be sure as there's no marking on this.

Hi David,

Dimension #2 is 0.5, as can be seen by the 8x (0.5) dimension on pin 18 of the drawing.

I need to check on dimension #1. It looks to be bigger than 0.25.

Hi David,

Dimension 1 is 0.325. You can determine it like this:

The full width of the pads across the part is 3.2 + 0.7. You can subtract from this the distance between pins 1 and 18, which is 2.5 - 0.25. The resulting 1.65 is divided by 2 to get the full width or pin 1. Then, you subtract dimension 2 (0.5) to get to 0.325.
