Multi-gapped ferrite

[Pafi]

I was searching for not an LPF. I try to understand what do you mean. "Best"? Lowest idle loss? Lowest DC resistance? Lowest size? Lowest distortion? Highest saturation current? Lowest EMI? Highest 2nd resonance freqency? Available? All of these? These requirements are contradictional. Are you going to find the optimal solution by collecting all available cores and measure them for all parameters and then calculate an overall "quality" parameter from all measured properties with weighting factors based on the type of the project? Or do you think you know a material that is simply The Best?

Lowest idle loss. Lowest DC resistance. Lowest size. Lowest distortion. Highest saturation current. Lowest EMI. yes pafi toroidal special high power class d special designed it exists

And wich is it? what material, who produces this special high power class d special design?

i spend time and money for that. only in private
