Tantalum - Polymer Capacitors

Tantalum-polymer capacitors are widely used for a variety of applications. They are classified according to the process of fabrication, the electrical characteristics of their electrodes and the nature of the dielectric material. The application of T528Z227M004ATE009 capacitors is mainly in nanoelectronics and other high frequency projects.

1. Principal of Construction

The T528Z227M004ATE009 capacitor is a surface mount tantalum capacitor constructed of an anode made of sintered tantalum powder and an oxide layer on its surface with a cathode of conductive polymer material. These capacitors have a low impedance and a high capacitance (up to 3300 μF).

2. Applications

Tantalum-polymer capacitors are widely used in communication, computing, automotive and medical electronics in which energy storage and signal filtering is required. These capacitors have very low leakage current and low ESR, making them ideal for use in low voltage applications. They are used for bypass and decoupling applications, where high performance and high reliability is critical. They are used for power supply filtering and noise suppression, clock signal filtering, circuit protection, voltage regulation, power supply ripple rejection, current sensing and signal filtering.

3. Working Principle

Tantalum-polymer capacitors work based on electrostatic principles. When the capacitor is connected to a DC voltage, charge flows from the capacitor’s anode to the cathode. The surface of the anode material is covered with an insulating material, called the dielectric, which is responsible for storing the charge. This dielectric material prevents the electron current from flowing freely, creating an insulation barrier between the anode and the cathode. As a result, the current that does the work of the capacitor is crested and the capacitor will remain charged until the applied voltage is removed.

4. Advantages

The primary benefit of using T528Z227M004ATE009 capacitors is that they offer excellent performance in high frequency applications with high temperature operating ranges. They are capable of storing energy in small physical packages, making them highly desirable for space-constrained product designs. These capacitors are also highly reliable, as they are able to withstand a wide range of environmental conditions including high temperatures, vibration, and humid air. Tantalum-polymer capacitors also offer relatively low ESR values and low leakage current, which makes them an ideal choice for high frequency and high power applications.

5. Disadvantage

The main disadvantage of tantalum-polymer capacitors is their relatively high cost. Additionally, these capacitors may be sensitive to current overloading and short-circuit conditions, which can cause them to become damaged and pose a safety hazard. Finally, they may also suffer from limited shelf life and leakage, leading to possible reliability issues.

T528Z227M004ATE009 capacitors are extremely useful for a variety of applications. Their construction and working principle make them suitable for high frequency and high power applications with excellent reliability and performance. In addition, their small size and low cost make them ideal for space-constrained product designs. However, these capacitors can suffer from limited shelf life and leakage, as well as current overloading and short circuit conditions, and have relatively high costs.
