>> 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.

Solvent resistance

Solution: isopropyl alcohol, solution temp:20-25℃ .The specimen shall be completely immersed in the solution for 1 min.  and the marking shall be rubbed with a brush 10 times. The above cycle will be applied 3 times and then the marking shall be examined visually. post test performance:  
a. Capacitance---within initial limit
b. DC Leakage---within initial limit
c. DF--- within initial limit
d. physical---Marking must be legible

Solder ability

Solder temperature:230±5℃,immersion times (solder):3±0.5sec, Immersion   in flux 5-10sec, .The specimen shall be immersed completely, post test performance:   The dipped portion of the termination is at least 95% covered by a new solder coating.
