Tantalum - polymer capacitors are electronic components composed of a tantalum powder core, a conductive polymer electrolyte and two metal plates on the positive and negative plates. The T530D477M004ATE006 is a specific model of tantalum - polymer capacitor. Its main application field is power supply design, while its working principle is based on Faraday’s law.

Tantalum - polymer capacitors have many advantages compared to other components, such as high volumetric efficiency, low equivalent series resistance (ESR), a wide range of temperature operating range, and low leakage current. The T530D477M004ATE006 capacitor is no exception, with a voltage range of 4.0V to 5.5V and a frequency range of 2.4 MHz to 6.0 MHz. In addition, it has a rated capacitance of 4.77 μF, an equivalent series resistance of only 10 mΩ, and a ripple current rating of 0.77A. With such specification, the T530D477M004ATE006 is especially suitable for high-reliability, high-density applications like switched mode power supplies, as well as low-frequency DC/DC converters.

To understand the working principle of the T530D477M004ATE006, we first have to revisit Faraday’s law. This law, coined by Michael Faraday in 18th century, states that when a conductive material is subjected to an external electric field, electric charges will be stored in the material. This phenomenon is also known as capacitance. In a tantalum - polymer capacitor, two plates located on the positive and negative ends of the tantalum powder core are attached to a conductive polymer electrolyte. When a voltage is applied across the two plates, the electric field created in the electrolyte will cause electric charges to move from one plate to the other. This movement of electric charges creates a capacitance, allowing the capacitor to store energy.

The T530D477M004ATE006 is a Tantalum - Polymer capacitor that is especially suitable for high power electronic design and power supply design. Its working principle is based on Faraday’s law, where the electric field generated by the applied voltage causes electric charges to move between the two plates, creating a capacitance that stores energy. In addition, its wide operating temperature range, low ESR, and high volumetric efficiency make it especially suitable for high-reliability, high-density applications.
