SV/H SERIES
(e) Flux
Use resin-based flux. Do not use flux with strong acidity.
(2) Reflow soldering
Keep in mind the following points when soldering the capacitor in a soldering oven or with a hot plate:
(a) Pattern design

The above dimensions are for reference only. Note that if the pattern is too big, the component may not
be mounted in place.
(b) Temperature and time
Keep the peak temperature and time to within the following values:
Solder temperature .............. 260
°
C max.
Time: 10 seconds max.
Whenever possible, perform preheating (at 150
°
C max.) for smooth temperature profile. To maintain the
reliability, mount the capacitor at a low temperature and in a short time whenever possible. The peak
temperature and time shown above are applicable when the capacitor is to be soldered in a soldering over
or with a hot plate. When the capacitor is soldered by means of infrared reflow soldering, the internal
temperature of the capacitor may rise beyond the surface temperature.
(3) Using soldering iron
When soldering the capacitor with a soldering iron, controlling the temperature at the tip of the soldering iron
is very difficult. However, it is recommended that the following temperature and time be observed to maintain
the reliability of the capacitor:
Iron temperature ......... 300
°
C max.
Time ........................... 3 seconds max.
Iron power .................. 30 W max.
