Products FAQs
Selected Category：Aluminum Electrolytic Capacitors
The pressure valve on an aluminum electrolytic capacitor is installed to mitigate the risk of ruptures or dangers caused by an increase in inner pressure during a malfunction.
However, certain compact products do not have a pressure valve.
Aluminum electrolytic capacitors may be used at the desired applied voltage provided the rated voltage is not exceeded.
There is no problem with using products in cases where the applied voltage is significantly lower than the rated voltage. However, there is the risk of increased current leakage if a high voltage is applied suddenly following a long period of use at an extremely low voltage.
Placement in high-temperature, high-humidity conditions could cause a moisture incursion from the seal into the inside of the capacitor. This could result in withstand voltage deterioration and reduced product endurance.
Please also consider the use of a resin coat or other moisture prevention measures.
We use ethylene glycol γ-butyrolactone as the main electrolyte solvent for aluminum electrolytic capacitors.
At present, we do not manufacture or sell aluminum electrolytic capacitors using electrolytes known as quaternary salts.
Aluminum electrolytic capacitors with a rubber seal, conductive polymer aluminum solid capacitors, and conductive polymer hybrid aluminum electrolytic capacitors are not subject to the MSL standards outlined by IPC/JEDEC.
Be careful of storage temperature, humidity, location, and environment as these can negatively impact electrical properties or the product performance of soldered lead lines.
Recommended reflow soldering conditions for aluminum electrolytic capacitors vary depending on the type, series, size, rated voltage, etc. Please refer to the product guide for details.

Aluminum electrolytic capacitors use electrode foils with two different types of withstand voltage.
As a result, the capacitors have polarity and there is the potential for rupturing if voltage in the reverse direction is applied.
Manufacturing Process of aluminum electrolytic capacitors is as follows.
Use a capacitor guaranteed for board cleaning and make sure that cleaning agent type and conditions are within the standards stipulated in the catalog or delivery specifications.
