CC2640R2F: 5X5 External Differential (5XD) Application Circuit Scheme question - DNM capacitors

Amit Maoz

Part Number: CC2640R2F

Hello,

In the 5X5 scheme for the external differential circuit for the CC2640r2f, there are 5 capacitors with the writing DNM, and no statement for their capacities.

What does the DNM mean, and what are the capacities for them?

Thanks,

Amit

What does "Do Not Mount" mean?

A DNM component is basically a placeholder in the layout. In some cases it could be that a component is needed in the future but not now. In other words, the layout needed the footprint but no component is going to placed.
