These capacitors are designed for use in communication, computer technology, automotive, and industrial electronic applications. Furthermore, these capacitors can be used in any electronic application requiring high capacitance and high reliability.

The M39003/01-5298/HSD series of tantalum capacitors can be used in high frequency, low voltage applications, such as in timing circuits, high-speed data transmission, and switching power supply circuits. These capacitors are also ideal for use in power regulation applications, such as DC-DC converters. Additionally, they can be used as energy storage devices in the output stages of amplifiers.

Working Principle

Tantalum capacitors are constructed from two different forms of tantalum, an electrolyte, and a dielectric. The two forms of tantalum used are sintered anode and powdered cathode. The sintered anode is made up of particles of electronically conductive tantalum that are fused together by sintering. The powdered cathode is made up of finely ground particles of chemically reactive tantalum.

The two forms of tantalum are connected to a semi-permeable membrane, which serves as the dielectric. At one side of the membrane, an electrolyte is applied. On the other side, the two forms of tantalum are connected to an electric charge. When a voltage is applied to the capacitor, an electric field is formed over the dielectric, which polarizes the two types of tantalum. This results in an accumulation of charge on the anode, forming an electrostatic field over the dielectric.

In operation, the voltage applied across the capacitor affects the capacitance of the capacitor. When a DC voltage is applied, the capacitor acts like a resistor, with the capacitance increasing as the voltage increases. At higher voltages, the capacitor allows some current to flow, but will limit the current at a certain level, which is called the breakdown voltage.

Tantalum capacitors are among the most reliable types of capacitors available. They are able to operate within a wide range of temperatures and are not susceptible to damage caused by vibration or shock. They also possess high capacitance per unit volume and have low series inductance, making them well suited for use in high frequency applications. The M39003/01-5298/HSD series of tantalum capacitors offer these advantages and are designed to meet the needs of a variety of applications.
