Tantalum - Polymer Capacitors

Tantalum Polymer capacitors are a type of supercapacitors, also known as electrochemical capacitors. They are made of a thin film of tantalum, an alternating layer of a conducting material (tantalum or aluminum) and a polymer material. These capacitors are known for their high dielectric strength, low ESR (equivalent series resistance), and low leakage current. They also exhibit excellent capacitance retention and excellent self-discharge capabilities.

One of the most commonly used varieties of Tantalum Polymer Capacitors is the T541X108M2R5DT8705. This particular type of capacitor is designed for high frequency pulse charge/discharge applications. Its small size and high current carrying capacity make it suitable for small devices, such as smart phone components, wearable electronic devices, and consumer electronics.

Application Field

The T541X108M2R5DT8705 is a high frequency pulse charge/discharge capacitor. It is commonly used in telecommunications and consumer electronics such as cell phones, laptops, and smart watches. It is also suitable for medical equipment, automotive applications, and instrumentation systems, among other uses.

The T541X108M2R5DT8705 is well-suited for applications that require a high-rate of charge/discharge along with high energy density, high power and high frequency operations. It can be used for wireless vibration and tactile sensors, wireless communication devices, high frequency digital-to-analog converters (DACs), and more.

Working Principle

T541X108M2R5DT8705 tantalum polymer capacitors are low-leakage, high-stability, and high-capacity hybrid capacitors. They are composed of a thin film of tantalum as the internal dielectric, sandwiched between two alternating layers of aluminum and Ta2O5. The two plates of each of the cells are connected in series by means of the tantalum oxide layer and the external contact is made through aluminum-plated titanium clips.

Within the capacitor, the tantalum layer acts as the dielectric, which provides electrical isolation and increases the capacitance gain. The aluminum substrate is used to absorb moisture, which in turn prevents corrosion and oxidation.

The two plates work together to form an electrical field, which is a measure of how much potential exists between the two plates. The amount of electrons between the two plates determines the capacitance. As the amount of electrons in the field changes, the capacitance changes.

When a voltage is applied to the capacitor, electrons flow from one plate to the other, which creates a charge. This charge can then be used to power electronic devices. The higher the voltage on the capacitor, the greater the number of electrons and the higher the accumulated charge.

Conclusion

The T541X108M2R5DT8705 is a type of tantalum polymer capacitors that have excellent capacitive performance, high energy density and high reliability. It is suitable for high frequency pulse charge and discharge applications, making it ideal for use in telecommunications and consumer electronics, automotive applications, and instrumentation systems. The working principle of these capacitors is based on the amount of electrons between the two plates, which determines the capacitance.
