T520V107M006ATE015

T520V107M006ATE015, also known as tantalum-polymer capacitors, are devices composed of a solid/polymer electrolyte. The solid part of the capacitor is a tantalum polymer composite encased in a metal can filled with organic solvent and some portland cement, while the other part is formed by the tantalum wire leads, the ceramic body and the dielectric material inbetween.

The tantalum-polymer capacitor is primarily used as a signal-level capacitor in high speed digital designs, especially those involving video and audio signal processing, as it is stable and reliable, and usually provides an improved signal-to-noise performance when compared to other alternatives. The capacitor also has a very low ESR (Equivalent Series Resistance) which makes them ideal for use in high frequency applications.

The working principle of the tantalum-polymer capacitor is based on the electro-chemical reaction between the polymer/solid tantalum electrolyte and the terminals of the capacitor. When a voltage is applied, the electrons move through the electrolyte and into the cathode, resulting in the formation of a thin film (the dielectric) on the capacitor walls. This process, coupled with the relatively low effective series resistance (ESR), allows for the capacitor to function over a range of high frequencies with excellent signal to noise performance. In addition, since the dielectric is formed by an electro-chemical reaction between the electrolyte and the terminals, the dielectric is not prone to breakdown from heat or humidity, leading to a longer life span than with traditional ceramic capacitors.

Due to their robustness, tantalum-polymer capacitors can be used in a wide range of applications, ranging from consumer electronics and telecommunications to automotive, industrial, and military electronics. Some of the most popular uses of the capacitor are in mobile phones, LCD monitors, game consoles, and computing components such as microprocessors and ASICs. With the recent move towards miniaturization and lightweight components, the capacitor is also becoming increasingly popular in miniature circuit boards, allowing designers to reduce thermal problems, size, and weight of the component.

In summary, the T520V107M006ATE015, or tantalum-polymer capacitor, is a reliable, versatile, and robust component which is becoming essential in many design applications. Its low ESR, excellent signal-to-noise performance, and long life span make it an excellent choice for consumer electronics, communications, automotive, industrial, and military electronics.
