Soldering Process
The implementation of the RoHS directive has resulted in the selection of SnAuCu (SAC) alloys or SnCu alloys as a primary solder.

Manual Soldering Recommendations
Following is the recommendation for manual soldering with a soldering iron.
Solderingirontiptemperatureshouldbesetat350°C(+10°Cmaximum),withthesolderingduration not to exceed more than 3 seconds.
2. The maximum temperature measured inside the capacitor: set the temperature so that inside the element the maximum temperatureisbelowthelimit.
