Tantalum capacitors, such as the M39003/01-5692, are electronic components with two electrical connectors designed to provide energy storage and high capacitance values in compact, cost-effective packages. Tantalum capacitors are made from mixtures of manganese dioxide or tantalum pentoxide electrodes sandwiched between impregnated dielectric layers of tantalum or other dielectrics. The material used to create the electrodes and dielectric layers are highly conductive, providing high efficiency and reliability to the capacitor.

Application Field

Tantalum capacitors are widely used in modern electrical and electronic systems. The M39003/01-5692 type of capacitor can be used in circuits where low ESR (Equivalent Series Resistance) is critical. They are excellent choice for decoupling, filtering, timing, and bias applications. Examples of these include power supplies, robotics controllers, communications systems, microwave, and audio devices.

The M39003/01-5692 type of capacitor can also provide energy storage in oscillators, pulse generators, and timing circuits. These devices are also used for high-decoupling power circuitry on SCR controls, motor drives, and industrial electronic equipment. Due to their high capacitance values, the M39003/01-5692 type of capacitor is also an excellent choice for buffer and DC link applications.

Working Principle

Tantalum capacitors, like the M39003/01-5692, work on the same principle as other types of capacitors: they store electrical energy in an electric field between a pair of conductive elements. In order to understand this better, the two conductive elements of the capacitor should be considered separately.

The first element is the anode, which is typically made of highly electrically conductive material such as tantalum or manganese dioxide. The anode forms one electrode of the capacitor and is connected to the electric circuit. The other electrode of the capacitor is the cathode, and is usually made of an organic polymeric material such as electrolyte. The anode and cathode are separated by a dielectric film or insulating layer which prevents electrical current from passing between them. When current flows through the circuit, an electric field is created in the dielectric layer, which creates an electric potential difference between the electrodes.

The capacitance of a component such as the M39003/01-5692 is dependent on the ratio between the area of the electrodes and the distance between them. A capactor with a large surface area of electrodes and a small distance between them will have a higher capacitance than one with a smaller area and a larger distance. The dielectric material memory effect on the capacitor also influences its capacitance. For a M39003/01-5692 type capacitor, this effect is caused by the organic polymer dielectric film, which gives the component its exceptionally high capacitance to size ratio as well as its dependability in extreme environments.

Tantalum capacitors are typically constructed with two terminals and a common ground, creating a three-terminal configuration. The most common arrangement is to have two terminals connected to the anode and one terminal connected to the cathode, though other configurations are also possible. When the capacitor is applied in a circuit, electrical energy is stored in the electric field generated between the electrodes.

Tantalum capacitors offer many advantages in electrical and electronic systems. They are highly reliable, have a high capacitance to size ratio, and are relatively small and inexpensive. The M39003/01-5692 type of capacitor is especially suited for applications requiring energy storage, low equivalent series resistance, and high capacitance values.
