I’m designing in SIM support in the MC modules family. All the design guides show adding ESD protection only.
There’re a few EMI/ESD devices with 100-ohm and 47-ohm series resistors as part of the ESD diodes protection.
I’m debating whether I should use this and if the series resistors would be needed with MC modules.
Perhaps the MC already has the series resistor built-in.
topic moved to correct section…
Decide the just add ESD diode because that’s recommended in the design guide.
