Tantalum Capacitors

Tantalum capacitors are electronic components used in a wide variety of applications, such as automotive, medical and aerospace industries. The M39003/01-2379/98 is a common type of tantalum capacitor. This article will explain the application field and working principle of the M39003/01-2379/98.

M39003/01-2379/98 Application Field

The M39003/01-2379/98 is a miniature, surface mount device designed for low cost, high performance switching and filtering applications. It is typically used for voltage and current filtering in automotive, medical, and aerospace applications. This type of capacitor is also often used in electric and electronic circuits, such as DC-DC converters, audio amplifiers, power supplies, and more.

The M39003/01-2379/98 offers excellent frequency stability, low leakage current, and ripple current capability. The capacitors are available in four physical sizes and offer superior performance in small, commercial, and industrial applications. The working voltage range is 10V–25V, and capacitance range is 0.1μF–470nF.

M39003/01-2379/98 Working Principle

Tantalum capacitors, including the M39003/01-2379/98, are two-terminal, non-polarized components. They are constructed from a base material of oxidized tantalum powder or sintered oxide pellets. This is then wrapped with a dielectric film of anodic oxide dielectric, forming a wound electrolytic capacitor. This type of capacitor is then typically hermetically sealed in a surface mount case, such as TO-220, TO-126, or flatpack type of package.

The M39003/01-2379/98 relies on a porous tantalum anode for its electrical properties. It is formed by treating the anode material with an electrolyte, which allows positive charges to fill the pores of the material. A polymer layer is then formed on the anode to act as the dielectric and a conductive layer is deposited over it to act as the cathode. This forms a capacitor layer, as the anode is surrounded by the dielectric and the cathode.

The M39003/01-2379/98 capacitor also use a chemical process called anodication, which coats the anode material with an insulating layer known as an anodic oxide. This enhances the reliability and stability of the capacitor and eliminates problems of leakage currents, fraction voltages, and temperature drift.

The primary advantages of using these tantalum capacitors include low equivalent series resistance, excellent capacitance stability, low resonance characteristics, and good mechanical strength. They are also well suited for applications where high stability, large capacitance, small size, and low weight components are desired.

Overall, the M39003/01-2379/98 is an ideal component for many high performance electronics applications because of its superb performance, reliability, and compact size. It is designed for low cost, high performance switching and filtering applications.
