Tantalum capacitors are devices made of titanium oxide layers with heavily doped tantalum electrodes for use in electronic circuits and equipment. The M39003/01-8028H is a type of tantalum capacitor that is used in various applications. This article will explain the application fields and working principle of the M39003/01-8028H.

Application Fields

The M39003/01-8028H is an ideal choice for applications where high reliability and long life are required. This type of capacitor is particularly suitable for use in high frequency pulse circuits, communication devices, and other circuits where a long operational life is needed. The capacitor’s low ESR and high capacitance is also well suited for many high-end audio applications. Additionally, the device’s high capacitance value and low ESR make it suitable for use in power supply filters.

Working Principle

The M39003/01-8028H is a tantalum capacitor featuring a porous anode. This anode consists of a highly-doped alloy of manganese and antimony that is pressed into a titanium oxide layer, and then vacuum sintered at a high temperature. The dielectric is composed of two titanium oxide layers. The first layer acts as the dielectric and the second layer acts as a barrier to prevent cathode-to-cathode leakage. The tantalum capacitor\'s cathode is made of a manganese-doped aqueous electrolyte. This combination of dielectric layers and cathode provide a reliable and stable dielectric material for the capacitor.

When the voltage is applied to the capacitor, current flows between the anode and the cathode. This causes electrons to be stored on the anode, where they form a negative charge. A positive charge is formed on the cathode via the electrolyte. The negative charge and the positive charge form a voltage differential across the two poles of the capacitor. The voltage differential creates an electric field across the capacitance, which helps to store the electrical energy within the electric field.

Conclusion

In conclusion, the M39003/01-8028H is a highly reliable and durable tantalum capacitor that can be used in a wide range of application. It is suitable for use in high frequency pulse circuits, communication devices, audio applications, and power supplies. Furthermore, it has a low ESR and high capacitance, which makes it an ideal choice for many applications. Its working principle involves the formation of a voltage differential across two poles of the capacitor, which helps to store electrical energy in the electric field.
