Today, I have received Power Line Filters and Ferrites

RP125-30-0-S It is single stage power line filter, and there is no Y capacitor, It can avoid a capacitor loss. and, much less power loss while production

RP230-30-4.7-S it is double stage power line filter with 4.7nF Y capacitor. I have RP230-30-10-S at the combiner box. maybe too much to try.

B64290L82X87 TDK 50mm ferrite core, I have used B64290L0082X065. But, I have decided to test with this ferrite becuase some reasons

1) X065 have 8~9A staturation current, but, this one have 21-22A

2) X065 has 10uH, and X087 has 4.460uH, so, I need more ferrites to get a similar result

Fair-Rite 0475164281 it is ferrite clamp, it is really hard to find a effective ferrite which can help to filter 100~120kHz noise. this is the lower frequency model, and will try on C-CT for isolate it also (even it is not make sense)
