Tantalum Capacitors - M39003/09-2007H Application Field and Working Principle

Tantalum capacitors, also known as tantalum-dioxide capacitors or (formerly) poly-tantalum capacitors, are miniaturized capacitors with the main component being a cylindrical solid or sintered tantalum anode and electrolytic oxide cathode. To withstand more strain, they are often enclosed in rubber and glass mixtures. M39003/09-2007H series are a kind of Axial Lead Tantalum capacitors with a wide range of application fields.

These M39003/09-2007H capacitors are primarily used within computers, consumer electronics, telecommunications, datacom, medical, defense, automotive, and industrial electronics equipment to perform tasks such as wave shaping, bypassing, coupling, decoupling, filtering, and energy storage. They have low leakage, low response time and a large voltage range.

Tantalum capacitors typically features a small size and higher capacitance than ceramic capacitors. These compact capacitors are mainly used in surface-mount design where they are available in small case sizes that allow them to be mounted on the surface of a PCB. Their small size and strong capacitance can be especially useful when compared with ceramic capacitors, which tend to have a larger size and lower capacitance.

The working principle of a M39003/09-2007H tantalum capacitor is very similar to that of other capacitors, which are composed of two terminals into which an electric current is allowed to flow through an insulating dielectric material. This dielectric can be either a vacuum or an insulating material like paper, ceramic, mica or tantalum oxide. The dissimilar materials of the capacitor terminals form an electric dipole, allowing the capacitor to store a charge. When a voltage is applied to the capacitor, electric charges of opposite polarity accumulate at the terminals. The amount of charge stored is proportional to the amount of voltage applied, with the capacitance of the capacitor being the constant of proportionality enabling the calculation of the amount of stored charge.

In the M39003/09-2007H series, the dielectric layer in the capacitor is made of tantalum oxide, which layers are deposited directly on the foil of the anode. The tantalum oxide layer is typically very thin, in the order of 1-2 µm. This very thin layer offers excellent performance with high capacitance values, low ESR and low dissipation factor.

The M39003/09-2007H series have several advantages that make them particularly well-suited for a wide range of applications, including increased capacitance, low losses, small size, and stable performance characteristics. The M39003/09-2007H capacitors are available in a range of case sizes, packaging and voltage ratings, making them suitable for a variety of applications.

In conclusion, the M39003/09-2007H series capacitors are designed for use in high reliability applications where capacitors need to be small, have a high capacitance value, operate at a wide voltage range, and have low leakage current. They have a wide range of application fields and are ideal for use in computers, consumer electronics, automotive, medical, industrial, and defense equipment.
