SV/H SERIES
4. Reverse voltage
Because the capacitors are polarized, reverse voltage should not be applied.
If reverse voltage cannot be avoided because of circuit design, the voltage application should be for a very short
time and should not exceed the following.
10% MAX. of rated DC working voltage @25
°
C
5% MAX. of rated DC working voltage @85
°
C
1% MAX. of rated DC working voltage @125

5. Mounting
(1) Direct soldering
Keep in mind the following points when soldering the capacitor by means of jet soldering or dip soldering:
(a) Temporarily fixing resin
Because the SV/H series solid tantalum capacitors are larger in size and subject to more force than the
chip multilayer ceramic capacitors or chip resistors, more resin is required to temporarily secure the solid
tantalum capacitors. However, if too much resin is used, the resin adhering to the patterns on a printed
circuit board may adversely affect the solderability.

The above dimensions are for reference only. If the capacitor is to be mounted by this method, and if the
pattern is too small, the solderability may be degraded.
(c) 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.
(d) Component layout
If many types of chip components are mounted on a printed circuit board which is to be soldered by means
of jet soldering, solderability may not be uniform over the entire board depending on the layout and density
of the components on the board (also take into consideration generation of flux gas).
