I was given the following capacitor by a spare parts shopkeeper when I asked for a polypropylene capacitor (to be used in RC snubber circuit for a mains load).
Can someone confirm this is the right kind? Will be connecting this is series with a resistor across a mains (230v) inductive load.
Looking through google images by searching he marking on the capacitor, it seems it could be either of the ones below
- Polystyrene Film
- Polyester Film
- Metalized Polyester Film
From the images I've seen, the Polypropylene ones carry a 'PP' mark on them. Either the one I have is not a Polypropylene or it's a cheap one with no markings.
Looks like I'll have to bite the dust and get a new properly marked one.
