When applying the IEC/EN 61000-4-2:2009 and IEC/EN 61000-4-5:2014 standards for our device, our consulting firm recommended bypassing the input power jack to the chassis ground using two 33nF capacitors based on the device's circumstances.
To ensure compliance, I reviewed the test requirements and found that a voltage of ±4 kV can be induced to the device's body.
Should the rated voltage of the mentioned bypass capacitors be at least 4 kV to handle this level of test voltage?
Furthermore, considering the ±8 kV air discharge immunity requirement, how does this impact the choice of components?
Lastly, from a technical perspective, would it be more suitable to use X1, Y2 type capacitors or high voltage generic capacitors?"
