Products FAQs
Selected Category：Aluminum Electrolytic Capacitors
When processing terminals for the purpose of mounting, make sure to fasten the lead line and make sure that no internal stress is imparted on capacitor.
We recommend using forming products for which terminal processing has already been conducted during the capacitor manufacturing process.
The rubber seal of radial lead-type aluminum electrolytic capacitors has concave and convex sections known as an air vent structure. During flow mounting, this structure helps prevent improper soldering due to thermal expansion of air existing between the rubber and substrate surface.
Aluminum electrolytic capacitors are components that are subject to wear. Product failure is judged based on service life , which is calculated using judgment criteria for electrical properties.
The measurement method and frequency of radial lead-type capacitors is standardized in accordance with JEITA RC-2003, and the value at a frequency of 40MHz is set as the ESL.
When measuring the ambient temperature of aluminum electrolytic capacitors, it is necessary to ascertain heat convection, heat radiation, heat conduction as accurately as possible.
Here, we introduce measurement methods using a dummy capacitor.
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.
