Tantalum capacitors, otherwise known as tantalum electrolytic capacitors, are an important element in electronic circuits. They are particularly well-suited to high-frequency applications and can provide extremely reliable results. They have been used in many consumer, aerospace, industrial and military applications, where reliability is essential. The M39003/01-2772 is one such type of capacitor that utilizes this technology. This article will explore both its application field and its working principle.

Tantalum capacitors are used in a variety of applications, ranging from audio, video, DC-to-DC conversion, filters, and signal conditioning to digital and RF applications such as board-level decoupling and voltage regulation. The M39003/01-2772 is uniquely designed with an oven-fired ceramic dielectric and a conductive polycarbonate casing with radial lead construction. This design provides superior CV characteristic, enabling longer life and higher breakdown voltages.

The working principle of a capacitor is based on electrostatics. The capacitor consists of two metal plates separated by an insulating material, known as a dielectric. When a voltage is applied to the device, charge accumulates on the plates and an electric field develops in the dielectric. The device then acts as a storage device, storing energy in the electric field. The energy stored is proportional to the charge on the plates and the dielectric’s property.

In the case of the M39003/01-2772, the device utilizes the higher breakdown voltage and improved CV characteristic enabled by its unique oven-fired ceramic dielectric to maximize performance. This dielectric works in tandem with the internal structure of the capacitor to form an opposite surface charge, creating an interelectrode distance and the electrostatic field. This field causes a change in capacitance, as current flows through the device. As with all electrostatic capacitors, the most efficient performance is achieved by keeping the interelectrode distance very small.

The M39003/01-2772 is an excellent choice for high-frequency applications due to its low equivalent series resistance (ESR) and ceramic dielectric. This dielectric also helps reduce temperature coefficient, giving the M39003/01-2772 a distinct advantage over other capacitor technologies in temperature sensitive applications. Its low ESR and high capacitance range make it an ideal choice for filtering applications as well.

In summary, the M39003/01-2772 is an exceptionally versatile capacitor that is well-suited for a wide variety of applications. The device’s unique oven-fired ceramic dielectric and conductive polycarbonate casing enable higher breakdown voltage and excellent CV characteristics, making it an excellent choice for high frequency, signal conditioning, filters, and temperature sensitive applications. Its low ESR allows for excellent performance in a variety of filtering applications. Finally, its radial lead construction ensures simple and easy mounting.
