Capacitor M368 any polar-connecting?

[Lene Larsen]

Hey again. I want to make a lightcontrol with some M368 and 344-capacitors. Can you tell me, if there is a +/pole and a -/pole at the capacitor? https://elektronik-lavpris.dk/p1308...lysdaemper/?osCsid=n6c3ehhfc1tpagb8pibmhac746
Kind regards from Lene

Sorry, I did not write the hole name mkt 368, but I saw the specifications of mkt 368, and the legs are the same, and there are no poles, https://www.ebay.co.uk/p/Philips-MK...UF-10-100-Volts-Pack-of-20-UK-Post/1922934205
Thanks athough for answering me, and sorry for my broken English

Hi.
Those capacitor are made for use with alternating current too. Look for the ~ AC symbol somewhere on them. Not polarized, use any side for ±
Usually canibalizable from discarded power supplies.

Hi Externet, I think I can handle it now. Although it is difficult to believe the importance of such a little capacitor. But I know there will be a lot of buzzer, if it is not there.

I do understand now

 

[Cannonball]

If it were polarized it would be marked.

Hi Cannonball, I can see now there is some different ways to mark the polarization.

ADDITIONALLY . . . .
What I particularly noticed that the link to parts that you gave were for mere 100 V rated capacitors.
And then . . .they just used a STOCK photo with completely different values.
With the AC levels that circuit could experience I would go for a X1 or X2 rated type of rating that are
associated with full line voltage use PLUS stringent safety specifications.
Otherwise I would be using any 630V rated poly capacitors that I had on hand, for safety.

Yah . . . .
YDERLIGERE. . . .
Hvad jeg specielt bemærkede, at linket til dele, du gav, var for blot 100 V ratede kondensatorer.
Og så . . .De har lige brugt et STOCK foto med helt forskellige værdier.
Med AC-niveauer, som kredsløb kunne opleve, ville jeg gå til en X1 eller X2-vurderet type rating, der er
forbundet med fuld-line spænding brug PLUS stringente sikkerhedsspecifikationer.
Ellers ville jeg bruge nogen 630V klassificerede poly kondensatorer, som jeg havde til rådighed for sikkerheden.

Hi 73's ed Edd, you see, this capacitors are for 400 Volt:

73's ed Edd, you are truely right, the capacitor of one of the links, are not quite the same.
