I have two capacitors, and they are both Metallized Polypropylene Film Capacitors, but they look pretty diferent to me, one is red, a little bit shiny with round corners like this:
and the other is yellow, opaque, with square corners and has a lot of information written on it:
Why are they so different even if they are in the same category of capacitors? Is it just aesthetics? different manufacturers? or are they used for different applications?
