NRF52832 dc-dc dec4 capacitor

[Oriol]

Hello all!

We are designing our first projects with NRF52832 and the DC-DC decoupling capacitor on DEC4 pin used in reference design is:

1uF 0603 X7R 16 Volts

Our question is, it's possible to change to 1uF 0603 X5R 10 Volts. X7R X5R is about temperature tolerance but we are afraid if we change to 10 Volts could be some problem with the DC-DC voltage spikes. We have large stocks in our warehouse of this capacitor with 10 Volts.

Thanks for your time,

Oriol

Hi Oriol,

using a 1uF 0603 X5R 10 Volts capacitor instead of a 1uF 0603 X7R 16 Volts capacitor should be just fine.

Best regards
