EMI can be used to suppress interference that is generated by the device or by other equipment in order make a device more immune to electromagnetic interference present in the environment.
Suitable for and special applications (low leakage current), mechanical equipment, treadmills, etc.
High quality and high performance components provide obvious filtering effect.
Used in most digital devices (especially switching power supplies) to suppress continuous and intermittent pulse interference.
It can also be used for white goods with frequency converters or frequency converters on control systems.
