Tantalum capacitors are passive electronic components that store electrical energy in the form of an electrostatic field. They are widely used in numerous commercial, consumer, and industrial applications. Applications range from powering small personal electronics, such as electronic watches and calculators, to providing power for aerospace and military applications.

M39003/01-5547H is a popular choice of tantalum capacitor due to its excellent properties such as high volumetric efficiency, low equivalent series resistance (ESR), and low total capacitance variation (CV). These features make it suitable for a wide variety of applications.

Application Field

The M39003/01-5547H tantalum capacitor is especially suitable for high-frequency and high-temperature operation due to its inherently low ESR and CV characteristics. This makes it a good choice for use in avionic, medical, automotive, and telecommunications applications.

The M39003/01-5547H is also well-suited for use in instrumentation, mobile electronics, and power supplies where improved temperature stability and higher reliability are required. Furthermore, these capacitors have been used in remote-controlled equipment and telecommunications equipment, such as modems and base stations.

Applications such as consumer, automotive, and defense electronics require a reliable, low-impedance power source, and the M39003/01-5547H offers this capability. These capacitors are also used in the computer industry, particularly auto-switching power supplies.

Working Principle

The M39003/01-5547H works as a two terminal chemical capacitance device. The dielectric is formed by chemically splitting the semiconductor oxide onto the surface of a solid tantalum powder core. This produces a thin, strongly adherent insulating barrier. The capacitance of the device is approximately proportional to the surface area of the dielectric. The broken surface area is then connected to the two metal end plates to form the electrical lead connection of the capacitor.

The M39003/01-5547H tantalum capacitors generally exhibit higher stability, lower leakage current, and improved temperature coefficient than other types of capacitor. The terminals are made from solid conducting material. The combination of the dielectric and relatively high material cost of tantalum, as compared to aluminium, results in higher cost as compared to general capacitor types.

Modern manufacturing techniques allow for tight tolerances, long service life, low ESR, and excellent high frequency characteristics to be attained from the M39003/01-5547H tantalum capacitors. This makes it ideal for applications where a high level of accuracy and reliability are of paramount importance.
