EMS immunity

It has become more important to know how much noise electrical devices can withstand in order to prevent problems with electrical devices from incoming noise.

This is called noise immunity, or EMS (ElectroMagnetic Susceptibility) which shows how much noise the equipment can endure.

There are various tests for noise interference such as electrostatic discharge testing, surge immunity testing, fast transient burst testing, voltage fluctuation testing, and electromagnetic field immunity testing.
