They help to reduce the level of electromagnetic interference in the block, or even completely prevent them. This interference is such a baddie: it could enter the power supply system at the input or output of the block and interfere with the operation of other electronic devices, cause failures and crashes. Without these heroes – EMI filters – there could be unpredictable consequences: interference with mobile communication and television, failure of cardiographs, pacemakers, routers may reboot etc.

That’s why our team strongly recommends you not to save money on EMI line filters.
