Hi,
We are currently implementing the nRF52840 in an upcoming product and we have a question regarding component selection for our configuration.
I've looked through the datasheet and resources - our design most closely matches reference circuit #3 (QIAA footprint). We've matched the components to be populated and their respective values; however, in some instances we want to diverge from what is listed in the reference circuit BOM available on the site (attached for reference):
Notably, we want to use some capacitors that have different dielectrics than what is listed on the BOM. For example, we prefer to use X5R capacitors rather than the X7S/R listed for things like C21 and C6/C20. Is there any particular design consideration put into selecting the dielectrics on the reference BOM or can we change them?
Thanks!
