T527I476M010ATE200

Tantalum capacitors are the most commonly used components in various electronic systems. In its application field, T527I476M010ATE200 is a common type of component found in many products, such as electronics, medical devices, and industrial equipment.

Basic Overview

Tantalum capacitors are constructed using small cylindrical cases and a tantalum metal powder as the electrodes. The powder is stored in a manganese dioxide (MnO₂) form by thin dielectric layers of metal oxide. In most cases, the cases are either marked with a wide variety of codes and numbers to indicate the type, size and other information about the component. Examples of this include the case code T527, the I76-M010ATE200.

Performance features

Tantalum capacitors are typically designed to offer high capacitance values while also offering a low Equivalent Series Resistance (ESR) and very low leakage current. In addition, they offer excellent high frequency performance and high stability over a range of temperatures. They also offer relatively high energy density, making them suitable for applications in tight spaces. The MnO₂-based structures also offer advantages in terms of vibration and shock resistance and ESR temperature stability.

Working Principle

Tantalum polymer capacitors are constructed of a series of alternating layers of metal oxide and tantalum powder. The structure of the material allows for the creation of a thin dielectric layer between the two electrodes that acts as an insulator to separate the electric field from the electrodes. This layer of insulation maintains a low capacitance value, and when a voltage is applied to the capacitor, the electrical current travels through the metal oxide layer, drawing charge from one electrode to the other. The capacitance of the component is determined by the ratio between the thickness of the metal oxide layer and the electrodes.

In addition to this, the MnO₂-based structure also offers improved performance characteristics such as stability, non-polarity, low inductance, and improved frequency performance. This material is also known for its high ESR and low leakage current. This makes these components ideal for a wide range of applications, including bypass, decoupling and filter capacitors.

Conclusion

Tantalum - Polymer capacitors are high performance components that offer a number of advantages, including high capacitance values, non-polarity, low ESR and low leakage current. They are highly suitable for a variety of applications, including bypass, decoupling and filter capacitors. The metal oxides in their structure offer high frequency performance, high stability over a range of temperatures, and vibration and shock resistance. This makes them the ideal choice for many electronic products and systems.
