Filtering and decoupling capacitors needed on eSIM

[Stephen Snyder]

Hello,

We are developing hardware with a soldered down eSIM.  Our previous LTE module vendor recommended 47pF capacitors on all the signal lines (CLK, RST, I/O) and 47pF // 100nF capacitor on the power line.  They stated it was for "EMI reasons".  Do you have any requirement for filtering capacitors for using eSIM with the nRF9160?  What would you recommend for power line decoupling?

We hope to remove the 47pF capacitors to save space.

Thanks so much,

Steve

Hello, 

Please note that due to Christmas holidays our R&D team are lower staffed than normal and that response time is increased.
