Does the nRF52832 have ferromagnetic components?

[Ed]

Hello I am using the nRF52832 in an application where it will be exposed to high magnetic field strengths (e.g. 30,000 Gauss) during normal use.  I wanted to know if there are any ferromagnetic components used inside the chip or any other circuitry that may be affected by these high fields.   For example maybe in the matching network

Hi,

I'm not sure if we have any numbers on this, but I'll ask around. It might take a couple of days before I have an answer for you.

Hi,

If DCDC is used, the required external 10uH inductor coil uses ferromagnetic core. It can be either shielded or open. Especially if open, coil core can become biased by magnetic field, affecting inductance, and probably DCDC operation.

For the radio, there are no ferromagnetic components inside the IC and hence there is no reason to expect any issues with strong magnetic fields.
