The best line capacitor to maximize power factor to a value of 1 is when you don't use a line capacitor. Any line capacitor will degrade the power factor of an SMPS. I'll quote what you linked: - the minimum value is based on the actual conducted EMI and what levels are acceptable for your application.
Hav-ing internationally recognized safety certifi cations, these capacitors are well-suited for applications that require keeping potentially disruptive or damaging line transients and EMI out of susceptible equipment. They are also an ideal solution when needing to suppress line disturbances at the source.
This is why the selected filter must still be tested in the actual system to verify results.
The key point is to understand that filters are com-posed of inductors and capacitors with parasitic/resonance efects that cause them to interact with the source/load im-pedances of the equipment/components. The filter should be placed directly at the exit point of the wire from the product. Good efective separation is essential.
Differential Mode Filtering. Common-mode filtering involves capacitors to ground and/ or a common mode inductor in series with both side of the line or lines. A common-mode inductor does not afect dif-ferential-mode currents except for whatever imperfect cou-pling exists (i.e., leakage inductance).
With a working voltage of 400 VAC in line-to-line (Class X)and 250 VAC in line-to-ground (Class Y) applications, these safety capacitors meet the impulse test criteria outlined in IEC Standard 60384. Meeting subclass X1 and Y1 requirements, these devices are certifi ed to withstand impulses up to 4 KV (X1) and 8 KV (Y1) respectively.
