Could some electronics guru please help ? I am totally confused by markings on polystyrene AC capacitors. Unlike electrolytic capacitors which have their capacitance and voltage values very clearly printed, the ones on AC capacitors is very cryptic. For example, a 0.1 uF 100V AC capacitor has the marking: "28 104J" What does this mean ? Does the "J" indicate some multiplier -- as10^-6 ? Any hints, suggestions would be very helpful. I have googled for this, but that has added to my confusion. Thanks in advance for your help.
