Introduction

Tantalum capacitors, designed to store and release electrical energy, are widely used in the automated systems and components found in many industries. The M39003/01-2286/98 is a part of the M39003 series of general purpose large-capacity surface mount capacitors. This paper will discuss the application field and working principle of the M39003/01-2286/98.

Application Field

The M39003/01-2286/98 is a large-capacity surface mount capacitor designed for board-level applications. The device is targeted for use in a wide range of applications, including consumer and industrial electronics, automotive, aerospace, and medical. Its proven reliability and consistent performance make it an ideal choice for high reliability, space-constrained applications.The device can be used in applications as diverse as pulse generators, inverters, switching amplifiers, timers, power amplifiers, transmitters, modulators, and waveform generators. Its ability to deliver high-amplitude signals make it especially suitable for communications equipment, though it can also be used in military, industrial, and medical applications.The capacitor is packaged in industry-standard microMELF and classicMELF packages, allowing for efficient integration onto board-level assemblies. Its low miniature package size allows for further miniaturization with minimal space on boards.

Working Principle

The M39003/01-2286/98 capacitor works on a simple principle. It stores electrical energy in the form of an electric field, between two conductive plates and dielectric material, and releases it when an external voltage is applied.The capacitor is constructed of two anodized aluminum plates, separated by a tantalum pentoxide dielectric layer. The anodized aluminum plates act as the two conductors, while the tantalum pentoxide layer acts as the dielectric material, storing the electrical energy.When an external voltage is applied, a current flows through the capacitor, bringing positive ions from one plate to the other, which creates an opposing electrical field. This opposing field attracts electrons to the opposite plate, and a build-up of electric stored energy occurs. When the electrical field reaches a certain threshold, the capacitor is said to be fully charged.When the external voltage is subsequently removed, the electrons return to their respective plates, and the stored energy is discharged. This discharge of energy is directed towards a suitable load, such as a motor, lighting, or other electronic component.

Conclusion

The M39003/01-2286/98 is a large-capacity surface mount capacitor designed for board-level applications. Its low miniature package size allows for miniaturization with minimal space on boards, and its proven reliability and consistent performance make it an ideal choice for high-reliability, space-constrained applications. The device works on a simple principle, storing electrical energy in the form of an electric field, between two conductive plates and dielectric material, and releasing it when an external voltage is applied.
