LT4320 based active rectifier

I hope you are doing well—as well as this curfew allows...
I tried ,just to distract myself a bit, to fill in a Mouser-Project according to the BOM. But is the one on post #1 still the valid one?

And, if you allow me to be a little bit lazy, I prefer to ask than to read through the thread: the rectifier would be primarily for my F4 project.

I already got the cans (CAP ALUM 47000UF 20% 35V SNAP), not sure if they fit your CRC PSU? Does it (the LT4320 rectifier) work with F4 (I guess, since FirstWatters have been okayed), and what would I have to adopt, if anything?

(As you easily see from those questions, I'm a novice)

Hi MLE,
let me answer one-by-one,
1. cap will fit perfect on the lt4320 crc psu pcb, no problems.
2. F4 will be fine for use of this psu.
3. BoM on page 1 for the LT4320 CRC-PSU-PCB is ok, no issues.
4. i am fine...., situation in India bad to worse, 😱 but still ok.

@Prasi, there are couple of caps C2/C2' which are rated per BOM 6.8uf 100v MLCC. I am not able to find any other replacements here in terms of values or ceramic/polyster type etc.. as rsdelivers and element14 have only 50v rated MLCC in 6.8uf and not more than that.

Thanks

higher voltage is a desirable quality , value is based on availability.
You could use 1-2uF also, not an issue.

Make sure that whatever voltage you use , you never exceed the cap rating with some margin.

Thanks Prasi, I hope you meant using say a 35v secondary transformer I may exceed 50vdc so anything above this should be good enough I guess. Using 63v rated big 10000uf caps on the big caps.
