Tantalum - Polymer Capacitors, including the T541X687M004AT8705, are advanced electrochemical capacitors made of a combination of tantalum and a conductive organic polymer. These devices combine high energy density and maximum life with relatively small size and excellent performance in difficult conditions.
These capacitors are electrolytic capacitors with a much longer lifetime than their electrolytic cousins. The T541X687M004AT8705 has a capacitance of 4.7uF, a voltage rating of 6.3V and a Ripple Current rating of 850mA. This combination of features makes it ideal for use in power decoupling, smoothing and filtering applications, where the device may be subject to high ripple currents and high temperatures.
Capacitors like the T541X687M004AT8705 are based on a tantalum anode and a conductive polymer cathode. The tantalum anode consists of a sintered powder of condensed tantalum atoms which acts as the charge storage medium. The cathode consists of a special conductive polymer which acts as the current collector and also contains a special electrolyte which allows the capacitor to charge and discharge.
In operation, the capacitor works on the principle of capacitance, where an electric charge is built up on the two sides of the capacitor and stored as potential energy. During operation, this electric charge is exchanged between the anode and the cathode, allowing current to be drawn from the device. As the power demands increase, the capacitor automatically adjusts to meet the corresponding demands.
The major advantage of the T541X687M004AT8705 over other types of capacitors is its excellent temperature stability. Unlike standard electrolytic capacitors, with the T541X687M004AT8705 the electric charge is not affected by the temperature or humidity changes, allowing the device to consistently deliver the same performance each time. In addition, its long life expectancy, combined with its relatively small size, allows it to be used in a wide range of applications in mobile, automotive and industrial electronic equipment.
The T541X687M004AT8705 has excellent frequency performance and its main advantage over other types of capacitors is its extremely low series inductance, which reduces its equivalent series resistance (ESR). This feature makes it a great choice for high power dc/dc converters and switching power supplies, where it can significantly reduce the ripple currents caused by switching. It also has a high self-discharge rate, so it is best suited for use in applications where frequent discharges are needed.
The T541X687M004AT8705 is also suitable for use in battery backedup systems, where its excellent temperature stability, long life expectancy and low equivalent series resistance make it an ideal choice. It is also particularly suitable for medical applications, where its excellent frequency performance and high reliability make it a great choice for vital circuits.
In conclusion, the T541X687M004AT8705 is a great choice for a range of applications where its excellent temperature stability, long life expectancy and low equivalent series resistance make it a reliable and efficient choice. Its small size, combined with its excellent frequency performance and high reliability, also makes it an ideal choice for a wide range of applications.
