Application Field and Working Principle

The M39003/01-3167/99 is a popular choice for the design of high-frequency switching power supplies and portable battery-powered electronics. It features a small size, low ESR, and high capacitance per unit volume. The capacitor is also highly reliable and exhibits good temperature characteristics. Its low DC leakage current minimizes power dissipation within the circuit, while its high-pulse rated capacitance ensures the high-frequency stability of the output power. The capacitor is constructed with an anode made of tantalum, a cathode made of manganese dioxide, and an electrolyte consisting of an aqueous solution of sulfuric acid. When a voltage is applied to the terminals, an electric current flows through the electrolyte and forms an electrolytic layer on the anode. This electrolyte layer stores a charge in the form of an electric field across the dielectric, thus increasing the capacitor\'s capacitance. Tantalum capacitors are particularly suitable for high frequency applications, as they have a very low equivalent series resistance (ESR).

Tantalum capacitors are used in a variety of applications where they are often preferred for their relatively long life and low ESR values, as well as for other specific advantages in a given application. They are commonly used in power supplies, audio amplifiers, memory chips, computers, and other electronic systems. They are also used in automotive audio systems to provide smooth sound and low distortion, and they are employed in various kinds of portable and military/aircraft electronics.

Tantalum capacitors are generally reliable and not prone to failure, although like all electronic components they are subject to failure or degradation under certain conditions. As a safety measure, tantalum capacitors should always be tested and inspected for signs of deterioration before being installed in an electronic device or system.

The M39003/01-3167/99 provides a reliable and versatile solution for a wide range of applications. It is small, reliable, and has low ESR and DC leakage current.
