ProtoDAC TDA1387 X8 project

[v12nut]

How do you really know they are MKP? It says it in the listing line, but not the part label. I wouldn't trust the Ali store. If you can find the spec sheet from the manufacturer. Also, the part will be pretty big in polypropylene at a 600V rating. If the lead spacing is not 27.5mm or 37.5mm, it will be hard to work with on the PCB.

If you can get the cap dimensions, you can tell if it is MKP or polyester (MKS). MKS are substantially smaller, about the size of MKC. Compare it to the size of a similarly rated WIMA MKP.

The cap dimensions are shown in the picture of the item and here is a link to the Manufacturer spec sheet

The item is C3D

I do appreciate that some sellers on Ali are less than truthful when it comes to descriptions.

thanks
