Tantalum capacitors, also known as tantalum electrolytic capacitors, are one of the oldest types of capacitors and are used extensively in a variety of electronic circuits and applications. There are numerous types of tantalum capacitors available, and the ones discussed here are the 173D475X0006U series of tantalum capacitors.

The 173D475X0006U is a surface-mount solid tantalum capacitor with a MnO2 solid electrolyte – commonly known as “Molded, MnO2 Tantalum Capacitors”

It offers excellent reliability, low ESR (equivalent series resistance), and excellent electrical characteristics. It has an operating temperature range of -55°C to +125°C, and a dielectric strength of 25 volts.

The 173D475X0006U is typically used in applications such as automotive and aerospace, industrial, military/defense, and consumer electronics including cell phones, digital cameras, MP3 players, and other portable devices.

The main application field for the 173D475X0006U is to provide long-term reliability in critical system applications. The tantalum capacitor design includes a solid tantalum anode, MnO2 dielectric, solid tantalum solution cathode, hermetic seal, and a wire lead.

The typical working principle for the 173D475X0006U is that the solid electrolyte acts as an ionic conductor with the electrons provided by the anode charging the capacitor and the electrons discharged by the cathode discharged from the capacitor. This is done by the solid electrolyte acting as a release valve for releasing ions from the anode and receiving them from the cathode.

As the capacitor is charged, an oxide layer forms on the surface of the anode and acts as a barrier between the anode and the electrolyte. This is caused by a re-direction of the electrons away from the anode and towards the electron-rich cathode. Theoretically, the oxide layer is completely exhausted after discharging and recharging the capacitor, however in the case of the 173D475X0006U, the oxide layer persists due to the MnO2 dielectric.

In addition, the 173D475X0006U also offers advantages over other types of capacitors due to its low ESR values. ESR is a measure of the resistance to a current flow through the capacitor, and the lower the ESR, the lower the power requirements for the device. This is particularly beneficial for applications where higher current levels are required.

Finally, the 173D475X0006U is also highly suitable for high frequency applications because the higher the frequency signal, the lower the ESR and the lower the required power. This makes the 173D475X0006U highly suitable for use in RF (Radio Frequency) applications.

In conclusion, the 173D475X0006U series of tantalum capacitors offer excellent reliability and low ESR values and provide a cost effective and reliable solution in a variety of applications. They are often used in automotive and aerospace, industrial, military/defense, and consumer electronics applications and can also be used in high frequency applications.
