1.7 Ripple Current
Gold Capacitors have a higher internal resistance
t h a n d o e l e c t r o l y t i c c a p a c i t o r s a n d a r e m o r e
susceptible to internal heat generation when exposed
to ripple current. When the temperature of the
element rises,a reaction current flows inside the Gold
Capacitor,generating reaction products and raising
internal resistance even further. This makes it
difficultt omaintain capacitance. Set the allowable
limit for the ripple current-induced rise in capacitor
temperatureto 3 C measured at the surface of the
capacitor.

imbalance in the voltages across the capacitors,
make sure that the voltage applied to each capacitor
will not exceed the Maximum operating voltage. If the

condition could result.
To prevent this from occurring, add a voltage-dividing
resistor in parallel with each capacitor, allowing for
the capacitor’s leakage current.
2. Mounting Considerations
2.1 Heat Stress During Soldering
Excessive heat stress may result in the deterioration
of the electrical characteristics of the capacitor, loss
of air-tightness, and electrolyte leakage due to the
rise in internal pressure.

and circuits. Plan for worst case failure modes such
as short circuits and open circuits which could
occur during use.

2.2 Circuit Board Patterns Under the Capacitor
Avoid circuit board runs under the capacitor as
electrolyte leakage could cause an electrical short.
2.3 Elevate the Gold Capacitor Above the PCB
If the capacitor is soldered driectly to a double-sided
PCB, a short circuit may occur between the capacitor
body and the wiring pattern. In the case of a through-
hole board, flux or solder blowing out of the holes can
shrink or break the external sleeve and possibly cause
internal damage to the capacitor.
2.4 Circuit Board Cleaning
Circuit boards can be immersed or ultrasonically
cleaned using suitable cleaning solvents for up to 5
minutes and up to 60 C maximum temperatures.
The boards should be thoroughly rinsed and dried.

any of the following environments.
(1) Environment where the capacitor is subject to
(2) Environment where capacitors are exposed to direct
