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.

A Tantalum Capacitors is comprised of a permeable tantalum center section surrounded by tantalum pentoxide ,A tantalum wire is inserted into the center section and then extends axially from the component .The tantalum pentoxide layer is coated with manganese dioxide graphite ,a silver conductive coating and (finally) solder. Since 1960,tantalum capacitors have improved due to advances and development of higher charge tantalum powders ,directly contributing to the design of smaller tantalum capacitors.

Kingtronics has manage TKT CKT and EKT series of tantalum capacitors, They are all widely used in many mass produced items of electronics equipment. Kingtronics ‘s Tantalum Capacitors are very popular in overseas market , For more informations please visit www.kingtronics.com , the detailed PDF will give you a satisfied answer.

Tantalum electrolytic capacitors exploit the tendency of tantalum to form a protective oxide surface layer, using tantalum powder, pressed into a pellet shape, as one "plate" of the capacitor, the oxide as the dielectric, and an electrolytic solution or conductive solid as the other "plate". Because the dielectric layer can be very thin (thinner than the similar layer in, for instance, an aluminium electrolytic capacitor), a high capacitance can be achieved in a small volume. Because of the size and weight advantages, tantalum capacitors are attractive for portable telephones, personal computers, and automotive electronics.

Kingtronics short for Kt (logo) produce tantalum capacitors since 1997, include dipped tantalum capacitors (through hole capacitors), general purpose chip tantalum capacitors (surface mount) and Low-ESR chip tantalum capacitors (surface mount).We have a full instruction about Tantalum Capacitors in our website www.kingtronics.com  each series of Tantalum Capacitors have detailed PDF and other information.

The steady-state and dynamic reliability of tantalum capacitors are influenced by several factors that can be controlled by the circuit design engineer. Key factors include voltage derating, ripple current, voltage conditions, maximum operating temperature, and circuit impedance.

Tantalum capacitors are known for their low electrical leakage (high leakage resistance) and ability to retain a charge over extended periods. They perform well in hot environments, withstanding temperatures up to 125°C, which makes them superior to standard aluminum electrolytic capacitors. However, tantalum capacitors can be relatively expensive, especially the military-grade versions. They are not particularly tolerant of heavy charge and discharge currents, particularly repetitive ones, and their effective series resistance (ESR) is higher compared to ceramic or aluminum electrolytic capacitors.

Since 1997, Kingtronics has been producing high-quality tantalum capacitors, including:

• Dipped Tantalum Capacitors (through-hole)

• General Purpose Chip Tantalum Capacitors (surface mount)

• Low-ESR Chip Tantalum Capacitors (surface mount)

Our tantalum capacitors are designed for a wide range of applications, offering high reliability and performance in demanding environments.

Tantalum is a key material in the electronics capacitor industry, representing approximately 68% of global demand. Its remarkable properties—high melting point, strength, ductility, reliability, resistance to corrosion, and thermal conductivity—make it an ideal and environmentally versatile choice for capacitors.

Tantalum capacitors are widely used in numerous electronic devices, including wireless devices, LCD monitors, DVD players, cell phones, personal computers, digital cameras, gaming platforms, telephone switchboards, and computer networks. Their unmatched capacity to store and release electrical charges ensures their critical role in the performance of these products.
