This is one of those times where I realize I still have a lot to learn. I'm sorting through some caps and realized I have what look to be red metallized polyester capacitors as well as mylar greenies. I'm a bit confused why the red ones would be so much smaller than the green ones at the same voltage (100v). Below is a pic of a 220nf greenie, 390nf red, 470nf greenie, and a 680nf red. As far as I know, these are both very similar types of poly caps - why are the red ones so much smaller?
Also- I'm not certain exactly what time of capacitors these are (below). Can't definitively say if the blue ones are ceramic, mlcc, or polyester - I figured the slightly taller one is ceramic and the shorter one is an mlcc...? No clue about the orange one!
