board materials (alumina substrates, FR4, FR5, G10,
PTFE-fluorocarbon and porcelanized steel).
Attachment:
P= Power dissipation in W at + 25 °C as given in
the tables in the product datasheets (Power
Dissipation).
R ESR = The capacitor equivalent series resistance at
the specified frequency

Solder Paste: The recommended thickness of the
solder paste after application is 0.007" ± 0.001"
[0.178 mm ± 0.025 mm]. Care should be exercised in
selecting the solder paste. The metal purity should be
as high as practical. The flux (in the paste) must be
active enough to remove the oxides formed on the

AC Ripple Voltage: The maximum allowable ripple

metallization prior to the exposure to soldering heat. In
practice this can be aided by extending the solder
preheat time at temperatures below the liquidous
state of the solder.

convection reflow, infrared reflow, wave soldering,
and hot plate methods. The soldering profile charts
show recommended time/temperature conditions for
soldering. Preheating is recommended. The
recommended maximum ramp rate is 2 °C per s.
Attachment with a soldering iron is not
recommended due to the difficulty of controlling
temperature and time at temperature. The soldering
iron must never come in contact with the capacitor.

The sum of the peak AC voltage plus the applied DC
voltage shall not exceed the DC voltage rating of the
capacitor.
The sum of the negative peak AC voltage plus the
applied DC voltage shall not allow a voltage reversal
exceeding 10 % of the DC working voltage at
+ 25 °C.
Reverse Voltage: Solid tantalum capacitors are not
intended for use with reverse voltage applied.
However, they have been shown to be capable of
withstanding momentary reverse voltage peaks of up
to 10 % of the DC rating at 25 °C and 5 % of the DC
rating at + 85 °C.
Temperature Derating: If these capacitors are to be
operated at temperatures above + 25 °C, the
permissible RMS ripple current or voltage shall be
calculated using the derating factors as shown:

Power Dissipation: Power dissipation will be
affected by the heat sinking capability of the
mounting surface. Non-sinusoidal ripple current may
produce heating effects which differ from those

Cleaning (Flux Removal) After Soldering: Molded
capacitors are compatible with all commonly used
solvents such as TES, TMS, Prelete, Chlorethane,
Terpene and aqueous cleaning media. However,
CFC/ODS products are not used in the production of
these devices and are not recommended. Solvents
containing methylene chloride or other epoxy
solvents should be avoided since these will attack
the epoxy encapsulation material.
When using ultrasonic cleaning, the board may
resonate if the output power is too high. This
vibration can cause cracking or a decrease in the
adherence of the termination. DO NOT EXCEED 9W/l
at 40 kHz for 2 min.
Recommended Mounting Pad Geometries: Proper
mounting pad geometries are essential for
successful solder connections. These dimensions
are highly process sensitive and should be designed
to minimize component rework due to unacceptable
solder joints. The dimensional configurations shown
are the recommended pad geometries for both wave
and reflow soldering techniques. These dimensions
are intended to be a starting point for circuit board
designers and may be fine tuned if necessary based
upon the peculiarities of the soldering process
and/or circuit board design.
shown. It is important that the equivalent I RMS value
be established when calculating permissible
operating levels. (Power dissipation calculated using
+ 25 °C temperature rise).
