Please read the following warning and cautions !!
The Electronic components shown in this catalog are designed and produced mainly for such general purpose electronic
equipment as audio and visual equipment, home appliances, office equipment and information processing and communication
equipment.
If you wish to use these components in medical equipment, transportation equipment, (automotive, train, ships, etc), aircraft,
spacecraft, security systems or other equipment that requires high security application, you are required to confirm application
through your own testing and own judgment.
Regardless of a component intended use, if high safety application is required, it is recommended that you shall establish a
protective or redundant circuit and shall conduct own evaluation test.
It is highly recommended that you shall follow our “Cautions for using”
Also it is recommended that you shall obtain technical specifications from Elna Co., Ltd to ensure that the component is
suitable for your intended use.
It is not our responsibility for any kind of problems without technical specifications.

About the Sn whisker
1. Sn whisker-generating mechanism on the lead wire
On the surface of the lead wire, Sn and aluminum will get mixed instead of getting dissolved.
The surface condition is complex, aluminum will expand due to the heat and humid causing the oxidation
and hydration. This reaction will cause the inner stress and influence the development of the whisker.
2. Generation control of the Sn whisker
In the past, Sn whisker was reduced by adding a lead(Pb). Aluminum electrolytic capacitor was also using
the Sn-plate with Pb on the lead wire.
But due to environmental regulation such as the “ELV” and “RoHS”, Pb was strictly prohibited since 2000.
Lead wire not containing the Pb was used, which caused the Sn whisker problem to happen again.
Since Sn whisker is influenced by the mixture of aluminum, method of reducing the aluminum on the welding
surface was to clean the lead terminal using the alkali.
However since the welding area of the large case size is larger compared to the small ones, whisker will
generate even if it is cleaned by alkali. This whisker will scatter outside of the capacitor and potentially
cause the short-circuit. Countermeasure of keeping the whisker inside the capacitor is being discussed.
3. Prevention of scattering of Sn whisker
In the past Sn-plate with Pb was used and recently plate with Bi is being introduced to prevent the whisker
from generating. However the whisker will still generate under the temperature and moisture condition.
Therefore, the current method of preventing the whisker will not completely prevent the whisker from
generating.
In our company, we are developing and supplying products with design of preventing the whisker from
scattering outside the capacitor.
This design corresponds to series such as the RJD and RJE for 105℃ use, RKD and RPK for 125℃ use.
If it is required for the other series, please feel free to make an inquiry.
