Help identifying a mystery cap

[LeftyStrat]

I have a kit of these caps, marked only 'Wima' on the container, but I can't seem to find anything online that looks like them. I'm trying to find out what their composition is. Sorry for the crappy cell phone photo.

Have you called the place where you got the kit? They may know something about your mysterious capacitor.

I picked it up at a yard sale many years ago. I suppose I could just give them a try in an amp. They are marked 600 volts.

[LeftyStrat]

Well, I went to Mouser and plugged in Wima, 600 volts, and 0.22 uf. Only thing left was polypropylene. They look different. So perhaps these are no long made.

Checked ebay and no wima's that look like these.

Looks to me like a Xicon metalized polypropelene.
I have some here but i cannot get the macro to focus on it.

That's a Xicon MPP ----- metalized polypropylene----- it is marked MPP on the cap itself------I don't know what it was doing in the Wima package, but it is definitely a Xicon MPP capacitor.
I'm using 220nF, 100nF, and 1uF Xicon MPP's in the current build on my bench.........................gldtp99

Thanks guys. The 'Wima' was hand written on the container, so maybe a mistake.

I used those Xicon MPP in my DBM #39 hot rod plexi and we could not be happier, sold that one and building another and will definitely use Xicon caps again.

Cheap generic caps. They work fine. No reason to be shy about using them.

Xicon. I like and use them often. No issues ever with them.
