inTroDuCTion
Due to the manufacturing technology and constant
improvements in tantalum powders, tantalum capacitors
have the highest CV (product capacitance x voltage) per
volume, very long life and high reliability.
These characteristics allow tantalum capacitors to be used
both in large volume markets like mobile phones and computers,
and in specialty markets such as space, aerospace, military
and railways.
TANTALUM CAPACITORS ALSO
HAVE THE FOLLOWING ADVANTAGES:
• Wide range of capacitance (less than 1 µF to more than 1000 µF)
• Wide operating temperature range ( -55°C to +125°C )
higher for non-standard types
• Electrical characteristics stable with temperature
• Low leakage current
• Very low ESR
• Electrical stability after long periods of storage
general inFormaTion
manuFaCTuring
ANODE AND INSULATOR
Tantalum capacitors have the highest ratio of capacitance per volume.
This is mainly due to the high dielectric constant of its insulator and to its large
surface area.
The basic raw material is a high purity (greater than 99.99%) tantalum powder
with a very fine granulation, compressed to form a cylinder or a parallelepiped
constituting the anode of the capacitor (positive plate).
The pellet is then sintered at high temperature (1500 to 2000°C), under hard
vacuum (10
-6
torr), firstly to purify the powder and secondly to obtain a strong
mechanical structure by welding of the particles.
The insulating part is obtained by anodization to a depth of the tantalum surface
which forms a tantalum pentoxide film (Ta
2
O
5
) with a thickness of about 16
angstroms per anodization volt. The dielectric constant is between 21 and 27,
depending upon the anodization conditions.
TYpe iDenTiFiCaTion – orDering inFormaTion
THE COMPLETE IDENTIFICATION OF A PRODUCT IS MADE UP OF:
• Type (or model)
• Tolerance
• Testing parameters (standard cata-
log part vs. tested in accordance
with MIL-SPEC standards)
• Rated capacitance
• Rated voltage
• Case size
• RoHS or non-RoHS
• For solid tantalum capacitors
specify tape or bulk packaging
THE TyPE
It identifies the basic capacitor (DCTSXX).
Example: DCTS1
THE RATED CAPACITANCE
Expressed in picofarads, the first two digits are significant figures; the third is the
number of zeros following:
Example: 102 = 10 x 10
2
pF = 0.001 µF
103 = 10 x 10
3
pF = 0.01 µF
334 = 33 x 10
4
pF = 0.33 µF
THE TOLERANCE
It can be expressed directly in % or identified by a code letter:
X0 = ±20% X9 = ±10% X5 = ±5%
Note:
The standard tolerance for tantalum capacitors is ±20%; if no tolerance
is given, it is considered as 20%. A 20% tolerance means in fact -20%
to +20% of the nominal value.
THE RATED VOLTAGE
It is expressed directly in volts (V), with three significant figures.
Example: 006 = 6 V DC; 050 = 50 V DC; 100 = 100 V DC
The case size:
It is indicated on the technical data sheets following the voltage
value and is generally identified by a letter code. It is important to give this
information because there can be, for the same type, a standard range and an
extended range in which the same value will be available in two different sizes.
THE TESTING PARAMETERS
C indicates a standard catalog part and S indicates tested in accordance with
MIL-SPEC standards.

THE MAIN APPLICATIONS OF TANTALUM CAPACITORS
CAN BE DIVIDED INTO THE FOLLOWING GROUPS:
• Filtering
• By pass
• Coupling
• RC time constant
• Energy storage
SOLID ELECTROLyTE: CATHODE AND ENCAPSULATION
The cathode is formed by manganese dioxide which is a grey semi-conductor.
It is obtained by dipping the pellets into a manganese nitrate water solution
which impregnates the internal structure; this solution is then decomposed in a
high temperature oven to obtain manganese dioxide. This operation is repeated
several times. The nature and quality of this semi-conductor greatly influence
the electrical parameters (especially the series resistance).
To finish the negative plate, a graphite coating and then a silver coating are
deposited on the outside surface of the manganese dioxide.
The positive nickel lead is welded on the tantalum wire and the negative lead
is either soldered with wire leads, or pasted with a silver epoxy for surface
mount models.
TANTALUM CAPACITORS ARE DIVIDED INTO
TWO GROUPS WITH SEVERAL SUB – GROUPS:
SOLID TANTALUM CAPACITORS:
• Metal cases
• SMD (CHIPS) types
WET TANTALUM CAPACITORS:
• Silver cases
• Tantalum cases
WET ELECTROLyTE: CATHODE AND ENCAPSULATION
The cathode (for wet tantalum capacitors) is formed by a sulphuric acid solution.
The anodized tantalum pellet is impregnated with this solution and then placed
in a silver or tantalum case, into which some equivalent gelled solution has been
previously deposited.
The case is then crimped on the internal PTFE bush to create the sealing. The
final steps are either the soldering of a glass metal seal, or the crimping of an
elastomer seal on the top of the case.
BURN-IN - SORTING - INSPECTION
All the products are then submitted to a final burn-in, with differing severities
depending upon the required characteristics of each type (temperature, voltage,
time,etc.).
Sorting, marking and inspection operations follow. These procedures are the
same for approved and non-approved parts (with exception of periodic testing).
