Gold Capacitors Technical Guide
Operating Techniques of Gold Capacitors
7. Connecting Capacitors in Series: Taking into consideration the possibility of an imbalance of voltage across
the capacitors, one needs to make sure that the voltage applied to each capacitor will not exceed the maximum
operating voltage.
If the voltage balance breaks down, an over voltage condition may result. To prevent this from occurring, add a
voltage-driving resistor in parallel with each capacitor, allowing the capacitor’s leakage current.
8. Environmental conditions: Avoid the use of capacitors at temperatures above the maximum operating
temperature. In this case, it may increase pressure to electrolyte vapor and release of gas by electrochemical
reactions. This will also result in a rise of it’s inner-pressure, which may cause electrolyte to leak and seriously
damage the capacitor.
9. Mounting considerations:
A) Double-side circuit board: Do not set wiring pattern directly to the mounted capacitor, and pass between
terminals. If the electrolyte leaks, short circuit may occur and “tracking or migrations” are anticipated.
B) Through hole board: Do not locate the capacitor close to circuit board. Solder blowing out of the holes may
cause a short circuit.
10. Do not apply any strong pressure to the capacitor after installation has been completed.
11. Do not use glue that contains halogen.
12. 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 temperature. The board should be thoroughly rinsed and dried.

• Please consult your local technical representative if you are using a solvent other than the ones listed above.
• The use of ozone depleting cleaning agents are not recommended in the interest protecting the environment.
13. Failsafe design: Install the following protection systems for a failsafe design to ensure safety if these products
are to be used in equipment where a defect in these products may cause the loss of human life or other signifi cation
damage, such as damage to vehicles (automobile, train, vessel, etc.), traffi c lights, medical equipment, aerospace
equipment, electric heating appliances, combustion/gas equipment, rotating equipment, and disaster/crime
prevention equipment.
• A protection circuit and protection device.
• A redundant circuit or other system to prevent an unsafe status in the event of a single fault.
• Please check or replace the Gold Capacitor periodically.
14. Before using the products, carefully check the effects on their quality and performance, and determine whether
or not they can be used. These products are designed and manufactured for general-purpose and standard use in
general electronic equipment. These products are not intended for use in the following special conditions.
•In liquid, such as water, oil, chemicals, or organic solvent
•In direct sunlight, outdoors, or in dust
•In vapor, such as dew condensation water of resistive element, or water leakage, salty air, or air with a high
concentration corrosive gas, such as Cl2, H2S, NH3, SO2, or NO2
•In an environment where strong static electricity or electromagnetic waves exist
•Mounting or placing heat-generating components or infl ammables, such as vinyl-coated wires, near these
products
•Sealing or coating of these products or a printed circuit board on which these products are mounted, with resin
and other material
•Using resolvent, water or water-soluble cleaner for fl ux cleaning agent after soldering.
(In particular, when using water or a water-soluble cleaning agent, be careful not to leave water residue)
