Understanding Mechanical Dimension of JTI-2450BM15A0002

[nahidalam]

Hi All,

I am new to PCB design, trying to make JTI-2450BM15A0002 footprint (https://www.johansontechnology.com/datasheets/baluns-matched/2450BM15A0002.pdf) in KiCAD.

In the datasheet, there is a red square (see mechanical dimension/terminal configuration). What is it? Is it a pad? Then there is no dimension, pad# for it?

Please suggest how should I approach it.

I think that is ground pad,you should connect to ground

Did you review the datasheet at all? If it's intended for ground connection, it must be shown in the suggested PCB footprint, but it isn't.

Think! How do you know about the right component orientation? Obviously the red square is the necessary pin 1 marking. You can see it in the PCB photo.

Thanks FvM. That makes more sense.

Now the question is, how do I indicate that pin 1 marking in the footprint?

May be add a small dot in the copper layer near pin 1. How do I do that and make sure it is just a copper dot, not another pad?

Or may be a different shaped pad for pin 1?

SMD component orientation is usually not marked in the copper artwork, but you can do if you think it's necessary.
