Ceramic Capacitor Aging: What to Expect
Soldering is a common process for deaing ceramic capacitors but is not the only way to perform deaging. Another common and equally effective method is to place the capacitors in a 150ºC oven for a min-imum of 30 minutes. The time above the curie point is not critical and once the capacitor reaches above the curie point, deaging occurs.

The impedance of a capacitor decreases according to the formula Z=1/jωC, until the resonant frequency. At that point, the impedance of the capacitor is the ESR. As frequency increases, the impedance is dominated by the equivalent series resistance and looks inductive, causing the impedance to increase. Figure 4 is a plot of the impedance of a capacitor versus frequency …
