Does the nRF52 withstand 10 V/m?

Hello!

I'm from a small company located in Austria. We are in the smart lock business and at the moment working on passing the CE certification with our newest hardware, which includes a nRF52 (BL652 Module from Laird). The hardware has to withstand an electric field strenght of 10 V/m, however the BL652 is only certificated for 3 V/m.

So there is my question, are there any nRF52 3rd party modules which are certificated for 10V/m, or has anyone advise on how to solve this problem? Is the nRF52 designed to resist electric fields of 10 V/m?

Kind regards,

Michael

    Unfortunately, the chip is not specifically designed to withstand electric fields of that magnitude. The chips are not tested for this kind of immunity so I'm afraid we don't have any numbers on this. We also do not have an overview of whether third party products are designed with this in mind.

    The best advice I can give at this time is to try and see if the chip withstands it, and to try to add shielding or external filtering if it fails.
