Tantalum capacitors are products with small volume, high capacitance and excellent performance. They were first developed by Bell Labs in the United States in 1956. They come in a variety of shapes and
Answer: Connecting two or more capacitors in series and parallel combinations allows almost any value and rating to be constructed for use in an application. For example, a capacitance of more than 60μF is required in a circuit for stable operation. The working voltage rail is 24 Volts dc with a superimposed ripple of 1.5 Volts at 120 Hz.
Tantalum polymer capacitors offer bulk level capacitance values similar to traditional tantalum capacitors with an MnO2 material system, as well as several other important advantages, including: · Significantly lower ESR. · Higher ripple current ratings. · Improved capacitance retention at high frequency.

At the core of this capacitor is a porous pellet of tantalum metal. The pellet is made from tantalum powder and sintered, or compressed at a high temperature, into a dense, spongelike solid. Just
THE BASICS OF TANTALUM CAPACITOR TECHNOLOGY. Most metals form crystalline oxides which are non-protecting, such as rust on iron or black oxide on copper. A few metals form dense, stable, tightly adhering, electrically insulating oxides. These are the so-called valve metals and include titanium, zirconium, niobium, tantalum, hafnium, and aluminum.
Wet tantalum capacitors have been utilized for many years in high energy storage applications where volumetric efficiency and high reliability are essential requirements.
