Tantalum Capacitors

Tantalum capacitors are a type of electrolytic capacitor which utilizes a tantalum solid electrolyte, where the metal acts as an anode and the oxide on the surface of the anode serves as a dielectric. Typical capacitance values range from a few picofarads up to 700 microfarads, with maximum working voltages from 4V to 125Vdc.

One of the advantages of tantalum capacitors is their low ESR (equivalent series resistance) compared to ceramic, aluminum polymer and other capacitors. This makes them excellent for high frequency applications, and for use in switching power applications, since they reduce energy loss and generate less heat.

The most common form of tantalum electrolytic capacitors utilizes manganese dioxide as the electrolyte, however, the use of a conductive polymer electrolyte instead of a liquid electrolyte allows tantalum capacitors to have higher capacitance values than manganese dioxide electrolytic capacitors. This Capacitance is also higher than that of aluminum electrolytic capacitors, but these capacitors have higher leakage current values and lower operating voltage ratings than aluminum electrolytic capacitors.

Another type of tantalum capacitor is one that uses a conductive polymer instead of manganese dioxide. These are known as polymer capacitors and are capable of higher capacitance values, higher operating voltages and higher ripple current ratings than manganese dioxide electrolyte capacitors. As with manganese dioxide tantalum capacitors, polymer capacitors have lower ESR and inductance than other types of capacitors.

299D106X0020CB6 Application Field and Working Principle

The 299D106X0020CB6 is a tantalum capacitor that utilizes manganese dioxide as an electrolyte. It has a capacitance value of 2,000µF, a working voltage of 10Vdc, and a tolerance of ±20%. This capacitor is widely used for decoupling and filtering, as well as energy storage, power supply and rectification, and signal filtering.

Tantalum capacitors work on the electrolytic principle and consist of a tantalum anode and a dielectric. The metal anode serves as the charge storage media, while the dielectric serves as the insulating layer and controls the flow of charge to the anode. The dielectric is formed by an oxide layer growing on the anode when electrical current is passed through the anode and the oxide layer increases the capacitance of the device. The anode is capacitively coupled to the dielectric and charges and discharges in accordance with the applied voltage.

In contrast to ceramic capacitors, the structure of tantalum capacitors allows them to have higher capacitance values and lower equivalent series resistance. The lower ESR values make the capacitors more effective for filtering and decoupling applications at high frequencies. Additionally, the low ESR values help to reduce the electrical power dissipation that occurs due to the charging and discharging of the anode.

The 299D106X0020CB6 is a cost-effective solution for those needing high capacitance and low ESR in an electrolytic capacitor. It is widely used in DC/DC converter applications, power supply filtering and rectification, noise suppression, and energy storage.
