ALUMINUM ORGANIC CAPACITORS

11. Temperature Stability
Mounted capacitors withstand extreme temperature
testing at a succession or continuous steps at
+25°C, -55°C, +25°C, +85°C, +125°C, +25°C in that
order. Capacitors are allowed to stabilize at each
temperature before measurement. Cap, DF, and
DCL are measured at each temperature; except DC
Leakage is not measured at -55°C.

19. Failure Mechanism and Reliability
The normal failure mechanism is dielectric break
down. Dielectric failure can result in high DC
Leakage current and may proceed to the level of a
short circuit. With sufficient time to charge, healing
may occur by one of two potential mechanisms. The
polymer adjacent to the dielectric fault site may over-
heat and vaporize, disconnecting the fault site from
the circuit. The polymer may also oxidize into a more
resistive material that caps the defect site in the
dielectric and reduces the flow of current.
Capacitor failure may be induced by exceeding the
rated conditions of forward DC voltage, reverse DC
voltage, surge current, power dissipation or tempera-
ture. Excessive environmental stress, such as pro-
longed or high temperature reflow processes may
also trigger dielectric failure.
