Gold Capacitors Technical Guide
Operating Techniques of Gold Capacitors
5. External sleeve
External sleeve is not intended to ensure electrical insulation, therefore, capacitors should not be used in an
environment that requires electrical insulation.
6. Heat stress during soldering
Excessive heat stress may result in the deterioration of the electrical characteristics of the capacitor, loss of vacuum,
and electrolyte leakage due to the rise in internal pressure.
•If the tip of the soldering iron touches the capacitor’s external sleeve, the sleeve will melt or rupture.
•Use the general reference charts to set soldering temperature versus time.
7. Brown extraction
Brown extraction may occur around the sealing part depending on use conditions. This extraction is electrically non-
conductive. Therefore, it does not infl uence in the electric characteristics.
4-2-2 Caution
1. This specifi cation guarantees the quality and performance of the product as individual components. Before use,
check and evaluate their compatibility when installed in your products.
2. Do not use the products beyond the specifi cations described in this document.
3. Electrolyte leakage: Electrolyte is used in the product. Misuse can result in rapid deterioration of characteristics
and its functionality. Electrolyte leakages damage printed circuit and affects performance, characteristics, and func-
tions of the circuit.
4. Over Voltage: If Gold Capacitor is used at a voltage exceeding its maximum operating voltage, not only is its life
shortened but it may cause capacitor to leak or rupture.
5. Polarity: Be sure to verify the polarity of the capacitor before use. If a reverse voltage is applied for a long period of
time, capacitor life is shortened and serious damage such as electrolyte leakage may occur.
6.Ripple current: Gold Capacitors have a higher internal resistance than electrolytic capacitors and are more sus-
ceptible to internal heat generation. As the temperature of the element rises, additional current fl ows inside the Gold
Capacitor, raising the internal resistance even further. This makes it diffi cult to maintain the capacitor temperature at
3°C (measured at the surface of the capacitor).
