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.
Vibration resistance performance is defined in JIS C5101-4, which outlines that performance should be guaranteed for a frequency range of 10Hz to 55Hz at maximum acceleration speed of 10G for two hours in the X, Y, and Z directions, respectively. For certain products, we guarantee performance at frequency ranges and maximum acceleration speeds that exceed the JIS standard.
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.
Aluminum electrolytic capacitors do not have a UL flammability standard and are to be handled as flammable products.
However, in some products, we do use parts and materials that have obtained a UL flammability standard (UL94 or UL224).
Dissipation factor (DF) is regulated as an electrical property of aluminum electrolytic capacitors.DF is one of the metrics used to express capacitor loss.
In an ideal capacitor, there is no resistance element and loss does not exist, so DF is zero.
ESD has no effect on aluminum electrolytic capacitors.
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.
