Selected Category：Aluminum Electrolytic Capacitors
ESD has no effect on aluminum electrolytic capacitors.
A rush current is a large current that flows instantaneously during power supply startup or at the start of charging.
For aluminum electrolytic capacitors, we set shock resistance that is compliant with JIS C5101-4.
Aluminum electrolytic capacitors do not experience changes in capacitance due to voltage bias.
This is because the aluminum oxide used as a dielectric does not have piezoelectric properties.
Capacitors with a seal featuring a pressure valve should not be used with the seal facing downward.
Also, if placing horizontally, position the pressure valve upward or position the anode terminal upward so that the pressure valve is facing horizontally.
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.
