Information for Elecsound tantalum capacitors
Type: dipped tantalum capacitor and SMD tantalum
capacitors
Elecsound Tantalum capacitors are widely used
in electronics design these days. Tantalum
capacitors offer a form of capacitor that
provides a very high capacity density. As a
result this form of capacitor has found
widespread use in many areas of electronics. In
view of its size and the attainable levels of
capacitance, these capacitors are widely used in
many mass produced items of electronics
equipment. The tantalum capacitor is similar to
the electrolytic capacitor, but using tantalum
within the construction of the capacitor it is
able to offer extremely high levels of
capacitance for any given volume. As such
tantalum capacitors are widely used in
electronics equipment where there is a need for
small size and a high level of capacitance. In
view of its advantages, the tantalum capacitor
is used in large volumes within the electronics
manufacturing industry.
Dipped type
tantalum capacitors
The most common form of
leaded tantalum capacitors in use today are the
"solid" tantalum capacitors. They offer
particularly small package sizes and as a result
they have been widely used in many areas of
electronics.
Leaded tantalum capacitors (solid tantalum
variety) are generally small and encapsulated in
epoxy to prevent damage. The capacitor marking
may be written directly onto the encapsulation
as figures, although many used a colour coding
system.
SMD tantalum capacitors capacitors
Tantalum SMD capacitors are widely used to
provide levels of capacitance that are higher
than those that can be achieved when using
ceramic capacitors. The capacitor technology
that is used within SMD tantalum capacitors is
based on the solid tantalum capacitor
technology. This is robust and enables very
small capacitors to be made.
For many years tantalum capacitors were used in
SMD applications because electrolytic capacitors
were not able to survive the high temperatures
of the soldering process. Now that electrolytic
capacitor technology has been developed to
withstand the soldering process, these
capacitors are now also widely used. Despite
this, the other advantages of tantalum
capacitors are employed in many circuits, and
they are still used in vast quantities.
As a result of the different construction and
requirements for tantalum SMT capacitors, there
are some different packages that are used for
them. These conform to EIA specifications.
