Requirements for Package-Sizes of Capacitors/Inductors used with nRF52840

[Ray Breslin]

Hello,

I am just curious wether there are any specific recommendations or requirements for the package-sizes of capacitors/inductors listed in the BOMs of the nRF52840-reference-designs (found here).

We are currently using the design #5 with the components from tab. 149 as reference and are planning to replace the 0603- with 0402-components.

I also checked a couple other topics in the forum like here and here, but so far I couldnt find any answer that specifically pointed out dos/donts for using 0603 over 0402 packages.

Any further thought or idea on this would be very much appreciated!

Kind regards,

Ray

Hi Harald, 

we have a white paper that covers the selection of decoupling capacitors for our nRF5 Series ICs, nWP030 - Power supply decoupling capacitor selection,  you can find it here. 

Best regards

That white paper link is 404, and I'd like to know more.
