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.

>Temperature stability >>>

Step NO.	TEMP.	CAPACITANCE	DCL	DF
1	+25℃	Within specified tolerance	Within original limit	Within original limit
2	-55℃	Within ±10% initial value	N/A	Within original limit
3	+25℃	Within ±5% initial value	Within original limit	Within original limit
4	+85℃	Within ±10% initial value	Within10X original limit	See table 1
5	+125℃	Within ±12% initial value	Within12X original limit	See table 1
6	+25℃	Within ±5% initial value	Within original limit	Within original limit

>Temperature cycle >>>

-55℃,room temperature,125℃ ,5 cycles 30min , Post test performance:
a. Capacitance---within ±5% initial value
b. DC Leakage---within initial limit
c. DF--- within initial limit

>Life test >>>

2000 hours ,+85℃,rated voltage or 2000 hours,+125℃,2/3 rated voltage, post test performance:
a: Capacitance---within ±10% initial value
b. DC Leakage---within 200% initial limit
c. DF--- within 150% initial limit

>Surge voltage >>>

85℃,1.15 rated voltage measurement is done after 1000 cycles of 0.5 minutes on 5.5 minutes off with 1000 Ω of series resistance. Post test performance:
a. Capacitance---within ±10% initial value
b. Leakage---within initial limit
c. DF--- within initial limit

>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.
