Tantalum capacitors, also known as Ta-capacitors, are electrolytic capacitors with tantalum electrodes. The M39003/03-0330H is a newly introduced series of thick-film chip tantalum capacitors from Vishay. It offers a wide range of applications, such as for use in high-performance control and power systems, as well as for space-saving designs. This series of tantalum capacitors boasts a high energy storage of up to 1,400Wh/kg, as well as high frequency response up to 20GHz.

The M39003/03-0330H series is designed to fulfill the job of PCs, solar modules, oscillator circuits, and other high power electronic applications. Its working principle is simple, yet effective. Firstly, it acts as a reserve for energy storage, storing the energy in the form of an electric charge between its surfaces. Secondly, it acts as a filter, allowing high frequency signals (such as those of a computer) to pass through, while blocking out lower frequency signals.

The working principle of a tantalum capacitor is based upon the principle of capacitance. In traditional capacitors, electrical charge is stored in electric fields between two metal plates separated by a dielectric. With tantalum capacitors, the electrical charge is stored between two plates that are insulated from each other. The electrical charge is supplied by a tantalum oxide which is deposited on the plates, forming the fixed and variable electrodes of the capacitor.

The energy that is stored and discharged within a M39003/03-0330H capacitor depends on the applied voltage, as well as on the temperature, pressure, and other ambient conditions. As the applied voltage increases, so does the stored energy. The higher the voltage, the greater the electric field between the plates, resulting in a stronger capacitive action. When the voltage drops, the capacitive action is weakened and the stored energy is released.

The working principle of the M39003/03-0330H series also includes self-healing. This is a unique feature in which if there is a breakdown or short circuit within the capacitor, the short circuit is automatically healed, thereby restoring the capacitor to its original operating condition. This process is made possible through the use of an electrically conductive polymer which acts as a bridge between the damaged plates.

In addition, the M39003/03-0330H also features high temperature tolerance and low ESR. This means that it is suitable for use in applications where there is a need to operate in extreme environmental conditions. The tremendous temperature tolerance and low ESR make it ideal for high temperature environments such as for automotive and aerospace applications.

In conclusion, the M39003/03-0330H series of tantalum capacitors are designed for applications that require high energy storage and filter functions. Its working principle is based upon traditional capacitance whereby electrical charge is stored between two metal plates separated by a dielectric material, with a tantalum oxide deposited on the plates. The capacitor also features self-healing and boasts high temperature tolerance and low ESR, making it suitable for a wide range of applications.
