|  >> Component Characteristics   >>Capacitance Capacitance is measured at 120HZ,less than 1.0 volts rms, at 25℃ Capacitance increases with increasing temperature. DC leakage current (DCL)  DC leakage current is the current that ,after a five minute charging period ,  flows through a capacitor when voltage is measured at 25℃ with full rated DC voltage applied to the   capacitor   through a 1000 ohm resistor in series with the capacitor. DC current increases with increasing temperature. Dissipation factor ( DF)  Dissipation factor is measured at 120HZ up to 1.0 volt rms maximum. DF increases with increasing frequency.
