Tantalum capacitors, also known as tantalum electrolytic capacitors, are capacitors that use tantalum as the anode material. They are also called tantalum electrolytic capacitors because their anode is formed by an oxidized tantalum surface. The name of this type of capacitor was derived by replacing the other two letters in the word "capacitance" with "tanta" and "lum," the chemical symbol for tantalum. The construction, principle of operation and application field of the 199D107X9016F6V1E3 tantalum capacitors will be discussed below.

Construction

Tantalum capacitors are polarized type capacitors and as such require careful orientation of the component leads and PCB pads during assembly. They normally consist of a molybdate sleeve, tantalum anode and a tantalum pentoxide dielectric, with a pellet of cathode material inside the sleeve. A wound element construction is also available, comprising of a metalized tantalum anode foil and electrolyte, encased in a metal sleeve and sealed with wax or resin. The equivalent series resistance (ESR) of these devices is much lower compared to aluminum electrolytic capacitors. The capacitance value is determined by the size of the anode and dielectric.

Principle of Operation

Tantalum capacitors function in the same way as any other electrolytic capacitor. When current is applied to the anode and cathode, ions of the electrolyte (in this case, molybdate and/or tantalum pentoxide) are released and form a very thin, non-conductive layer on the anode, known as the solid electrolyte interface (SEI). This layer increases the device\'s electrical resistance. The cathode material acts as a reservoir for the electrolyte, and the device self-generates its own charge, thus maintaining its capacitance.

Application Field

Tantalum capacitors are ideal for oscillator, switched-mode power supplies and filters. They are also suitable for surge current and high-temperature applications, such as automotive electronics and high-power applications. Tantalum capacitors are also preferred in audio applications, as they have low noise and distortion characteristics. Due to their wide range of applications, tantalum capacitors are found in a variety of systems and devices, including cell phones, computers, radio transmitters and receivers, video games, medical devices and high-energy power systems.

Conclusion

The 199D107X9016F6V1E3 tantalum capacitors have a wide range of applications due to their excellent characteristics, such as high capacitance-to-volume ratio, low voltage ratings and low ESR. They are well-suited for use in oscillator, switched-mode power supplies and filters, and for surge current and high-temperature applications. Furthermore, these capacitors are also ideal for audio applications due to their low noise and distortion characteristics. As such, these capacitors are used extensively in diverse fields and have earned a place among the various types of electrolytic capacitors used today.
