Is this capacitor polarized?
I recovered a few capacitors of this style from an old cassette player. As far as I can tell, it seems like Mylar film, but the “100⊖” marking has me wondering. Is this some peculiar shaped tantalum capacitor, or is the indicator not a polarity marking?

Given neither end has any markings to indicate polarity, no broad lines coming down an end, I'd say this is 0.010uF 100Volt.

My guess would be 10 nF mylar (first 2 digits = 10, third = multiplier 10^3 pF) 100 V. J = 5 %. I reckon that 10 nF is too small for a tantalum so I don't think this is polarized.

Me, too. I have no clue what the dingus is after the 100 - maybe a really little logo? But it's the right size and shape to be a mylar cap with that value.
