Tantalum capacitors are capacitor devices that use the dielectric of tantalum pentoxide, the charge storage media of the capacitor device. The tantalum capacitor is characterized by its high volumetric efficiency, long life and stable electrical parameters, wide temperature range and a wide selection of capacitance values. The basic structure of a tantalum capacitor is a tantalum anode, which is formed by sintering a molybdenum oxide onto a compacted powder core of tantalum, sandwiched between two gold electrodes, the cathode and the electronic ground.
M39003/01-2296/PR capacitors are chip and embedded tantalum capacitors made of tantalum foil anode, an electrolyte and a sintered anode as the base material. The chip has an external wall and a laminated anode body, the oxide, which acts as the dielectric. The cathode of the capacitor is connected to a positive voltage source, usually a bypass capacitor, and the anode is connected to ground. The operating frequency of the capacitor is 10-20 or 50-200KHz, depending on the temperature and electrical environment.

The working principle of M39003/01-2296/PR capacitors is based on the dielectric of tantalum pentoxide. It stores energy in an electrical field, which enables it to perform the capacitive role. The capacitor forms an electron layer on the surface of its tantalum anode that acts as a barrier between the anode and cathode, thus ultra-high voltage can be achieved.
The capacitor’s ability to absorb an electric charge quickly gives it its high volumetric efficiency. As the charge increases, the field created by the electric charge strengthens, allowing the capacitor to hold larger charges. The clamping voltage of the capacitor is also increased, resulting in higher voltage ratings for the capacitor. Furthermore, the electric charge applied to the capacitor is stored equally on its anode and its cathode, giving it its stable electrical parameters.

The application field of M39003/01-2296/PR capacitors covers a wide range. It is used in a variety of applications including bias circuits in communication equipment, TV sets, computer equipment, automotive digital systems and other electronic circuits. For example, in communication equipment, the capacitor can be used in a bias circuit for low noise processing between the receiver and transmitter, and in automotive digital systems, it can be used in digital motors and controllers to realize anti-interference for data transfer. The capacitor is also widely used in switching power supply and converter circuits and other DC and RF circuits, to store electric charge and filter the interference.

In conclusion, M39003/01-2296/PR capacitors are chip and embedded tantalum capacitors featuring high volumetric efficiency, long life and stable electrical parameters. Their application covers a wide range of areas, such as communication equipment, TV sets, computer equipment, automotive digital systems and other electronic circuits. Thanks to its dielectric of tantalum pentoxide, the capacitor can store energy in an electric field, allowing it to perform the capacitive role.
