This is expressed in
picofarads. The first
two digits are the
significant figures.
The third is the
number of zeros to
follow.
This is expressed in
volts. To complete
the three-digit
block, zeros
precede the voltage

additional cost. Color coding shall be as mutually
agreed upon by Vishay Sprague and the customer.

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.

equal to 10% of the DC rating at + 25°C and 5% of the
DC rating at + 85°C and 1% of the DC rating at +85˚C
and 1% of the DC rating at +125˚C.
4.
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:
or, from the formula:

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 shown. It is
important that the equivalent Irms value be
established when calculating permissible operating
levels. (Power dissipation calculated using + 25°C

7.2 Soldering: Capacitors can be attached by
conventional soldering techniques - convection,
infrared reflow, wave soldering and hot plate
methods. The Solder Temperature/Soldering Time
chart shows maximum recommended time/
temperature conditions for soldering. Attachment
with a soldering iron is not recommended due to the
difficulty of controlling time at temperature.
8.
Cleaning (Flux Removal) After Soldering: The
695D is compatible with all commonly used solvents
such as TES, TMS, Prelete, Chlorethane.
Solvents containing methylene chloride or other
epoxy solvents should be avoided since these will
attack the epoxy encapsulation material.
9.
Recommended Mounting Pad Geometries: The area
under the tantalum wire nib should not be metalized on
the PC board. The nib must have sufficient clearance to
avoid electrical contact with other components. The
width dimension indicated is the same as the maximum
width of the capacitor.This is to minimize lateral
movement.

Printed Circuit Board Materials: The 194D is
compatible with most commonly used printed circuit
board materials (alumina substrates, FR4, FR5, G10,
PTFE-fluorocarbon and porcelanized steel). If your
desired board material is not shown there, please
contact the Tantalum Marketing Department for
assistance in determining compatibility.

7.1 Solder Paste: The recommended thickness of the
solder paste after application is .007" ± .001"
[1.78mm ± .025mm]. 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 metallization prior to the exposure to soldering
heat. In practice this can be aided by extending the
solder preheat time at temperatures below the
liquidious state of the solder.
