Tantalum capacitors are a type of electrolytic capacitor, which utilizes a formation of tantalum metal as one of its electrodes. The principal advantage of tantalum capacitors is their very small size compared to other capacitors of similar capacitance. Because of this, an increasing number of electronic devices in current use today incorporate tantalum capacitors. The M39003/01-7246/HSD type of tantalum capacitor is a high-energy density device that combines high-temperature operation, long service life, and reliable performance.

This type of capacitor incorporates a solid tantalum anode, an electrolyte-surrounded tantalum pentoxide dielectric, and a vapor-deposited homogeneous layer of platinum on the cathode plate. This combination of tantalum metal and stabilized tantalum pentoxide together form a dielectric system with a very high dielectric strength. The two layers of tantalum oxide and tantalum metal also provide a large amount of capacitance which is then further increased by the addition of the thin platinum layer. This combination of materials and construction method gives the M39003/01-7246/HSD a very high volumetric efficiency.

The M39003/01-7246/HSD is mainly used in applications where silvered mica capacitors cannot provide sufficient energy density, due to their limited size. Typical applications include filter capacitors, Class D audio-visual amplifiers, pulse-width modulated motor drive systems, and motor control systems. It is also suitable for use in automotive applications, such as electronic fuel injection systems, airbag igniters, and ABS brake systems.

In terms of working principle, the M39003/01-7246/HSD is similar to other electrolytic capacitors, with the difference being the choice of materials and its unique patented design. When an electrical potential is applied to the capacitor, the anode forms an electric field and an electric current flows through the electrolyte and then onto the cathode. This in turn causes the metal oxide on the anode to dissolve into the electrolyte. The amount of current consumed depends on the value of the applied voltage. As a result, the anode collapses and the stored electric charge is discharged. The same process is also reversed when the applied voltage is negative.

The M39003/01-7246/HSD tantalum capacitor offers a reliable and high capacitance in a very small package. Combining the high-temperature operation, long service life, and reliable performance, this type of capacitor can be used in a variety of applications, ranging from audio-visual amplifiers to automotive electronic systems. It is also an ideal choice for applications that require the highest efficiency, such as filter capacitors and pulse-width modulated motor drive systems.
