Hello
I plan to use this power module:
https://www.mornsun-power.com/html/pdf/LS15-23B12DR3.htmlthe thing i want to ask for is C1 which should be connected between pins 3 and 4. It shows a polarized capacitor and requires 450v rating, either 33u or 47u. My choice is an electrolytic of such ratings. it is very expensive compared to others too, even from LCSC.
However, since it is on the AC side, won't this damage it being polarized?
datasheet says:
C1 is used as filter capacitor with AC input (must be connected externally) and as EMC filter capacitor with DC input (must be connected), and it is
recommended to use the capacitor with ripple current >400mA@100KHz
I also ran out of space but will manage to do it if I squeezed in a smaller footprint than 16mm diameter one.
i could fit those:
lelonNippon chemi-con -> can it be trusted to be new and ok from LCSC?
CapXon --> i read here that it is a good brand. this cap fits specs.
^ those are 47u, the 33u ones are noticeably cheaper.
any recommendation?
is my choice of elec. cap correct here?
