do you know where to get information about aging in each type of capacitor, how the capacitance is changed by time. the one I am most interested is matallized polyester film capacitor, which does aging a little, but in reality, it is not quite ture.
Thank you for everyone who contribute your knowledge to it.
According to asoon recommanded website, it says that film capacitors is aging only 1% for its life time.
But one of my capacitor is aging 10-20 percents, and it is Metallized Polyester
Film capacitor(ECQUL , 0.15uF, 275V). Anyone knows why this is happening .
