Here, we display time-based changes in leakage current. As seen from this graph, the leakage current value gets smaller and stabilizes as time elapses. The standard value for leakage current is set to a value that provides a very significant margin relative to actual performance.
About the maximum allowed torque on terminal screws when mounting a screw terminal type aluminum electrolytic capacitor and recommended torque when tightening metal mounting bands.
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.
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.
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.
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.
