Abstract: The invention relates to an electromagnetic interference (EMI) filter (100), having line-side terminals (L1-L3) for connecting to an electric supply(S) and load-side terminals (L1′-L3′) for connecting to a load device (L), the EMI filter (100) comprises a load-side passive EMI filter stage (1) connected 5 to the load-side terminals (L1′-L3′) and is configured to suppress common-mode and differential-mode noise. The EMI filter (100) also comprises a line-side active EMI filter stage (3) connected to the line-side terminals (L1-L3) and is configured to suppress differential-mode noise, and at least one intermediate active EMI filter 10stage (2) located between the load-side EMI filter stage (1) and the line-side EMI filter stage (3), configured to suppress common-mode noise. The invention relates also to a method for manufacturing the EMI filter (100).
