What is Electromagnetic Interference?

Electromagnetic interference is described as conducted, radiated or magnetically induced voltage which degrades, obstructs or repeatedly interrupts the desired performance of electronic equipment. There are four fundamental interference sources:

-       Man made noise

-       Electromagnetic pulses through nuclear reactions

-       Electrostatic discharge

-       Cosmic noise


What is an EMI filter?

An electromagnetic interference filter is an electronic passive device used to suppress conducted interference present on a signal or power line. EMI filters are used to suppress interference generated by the device or other equipment to protect a device from EMI signals present in the environment.
