Tantalum-Polymer CapacitorsTantalum-polymer capacitors are a type of capacitor which uses a tantalum-based porous electrode and a polymer electrolyte. The porous electrode is made of a high purity powder which is pressed into a block and connected to the element terminals. The porous electrode allows for a large surface area which allows for a higher capacitance. The polymer electrolyte allows for an efficient transfer of charge and improves the electrical conductivity between the element and the electrolyte. Tantalum-polymer capacitors offer a wide range of applications due to their high capacitance and low equivalent series resistance (ESR).T541X476K030DT8710 is a type of tantalum-polymer capacitor commonly used in a variety of applications. This capacitor is designed with a metal-oxide film on the tantalum layer. This metal-oxide film allows for greater charge transfer between the tantalum and the electrolyte. The T541X476K030DT8710 offers a capacitance of 4.7uF and an ESR of 0.3ohm. The size of this capacitor is 4.76 x 7.94 x 1.09mm which makes it an ideal choice for high integration applications such as mobile phones, portable audio devices and wearable devices.The application field of tantalum-polymer capacitors includes various industries such as automotive, industrial, and consumer electronics. In automotive field, these capacitors are mainly used for power modules and DC/DC converters. In industrial and commercial applications, they are used for power supplies, communications, measuring and testing equipment, and high-end audio systems. In consumer electronic products, they are used for audio systems, computer peripherals and batteries.The working principle of tantalum-polymer capacitors is based on the charge transfer process. The porous tantalum layer acts as an anode, while the electrolyte acts as a cathode, and the ions form an electric double layer (EDL) at the interface between the two. When a voltage is applied, the ions in the EDL start to move, resulting in a charge transfer to the other side. As charge is exchanged over time, energy is stored within the capacitor, thus providing capacitance.The superior performance of the tantalum-polymer capacitors is due to their low ESR. This is due to the low equivalent series inductance (ESI) which is mainly caused by the metal-oxide film which reduces the total impedance. Of course, the capacitance value is also important for many applications such as power converters and other similar applications. The combination of high capacitance and low ESR makes tantalum-polymer capacitors ideal for use in high power applications.Overall, tantalum-polymer capacitors are a great choice for applications where high capacitance and low ESR are important. The T541X476K030DT8710 is an excellent solution for those applications where a low-profile component is required. Its metal-oxide film helps to reduce the ESR and ESI, making it suitable for use in high-end audio systems and other high-power applications.
