TANTALUM-POLYMER CAPACITORS

Tantalum-Polymer capacitors are a type of capacitors based on the combination of permeable metal and a polymer. Tantalum-Polymer capacitors are available in both surface mount and through-hole packages, making them suitable for a wide variety of applications. They are used in many applications, ranging from communications to medical equipment. The 2R5TAE470M is a popular tantalum-polymer capacitor. In this article, we will discuss the 2R5TAE470M application field and its working principle.The 2R5TAE470M is a surface mount tantalum-polymer capacitor with a capacitance of 470μF and a voltage rating of 6.3V. These capacitors are designed for a wide range of applications, including power management, commercial and industrial applications. The dielectric of the capacitor is formed by a thin porous layer of tantalum surrounded by a polymer that is overlaid onto the metal film. The thin metal film acts as the conductive electrodes. The film also acts as a shield to protect the capacitor from external electrostatic fields.The working principle of the 2R5TAE470M capacitor is based on the capacitor’s ability to store energy in the form of electric charge. When an electric charge is applied to the capacitor, it stores the charge in two layers, one positive and one negative. The two layers are separated by an insulator, which is the dielectric of the capacitor. The dielectric acts as a barrier, allowing the charge to be stored on the two layers. When a voltage is applied, the electric field created between the two layers of charges causes a current to flow. This current is used to provide power to the device that the capacitor is being used with.The 2R5TAE470M capacitor is a low-ESR (equivalent series resistance) capacitor, which means it can store more energy than a standard capacitor, despite having the same capacitance. This is because the dielectric of the 2R5TAE470M has a lower dielectric constant (K) than standard capacitors, increasing the energy stored by the capacitor. This makes it an ideal choice for applications with high power requirements, such as power supplies and voltage regulation circuits.The 2R5TAE470M capacitor is also durable and reliable due to its high temperature tolerance. The capacitor is rated to operate up to a temperature of 125°C, which is well above the typical operating temperature of digital circuits. This makes it suitable for use in harsh and extreme environments, such as automotive applications.In conclusion, the 2R5TAE470M is a versatile and reliable capacitor that is suitable for a wide range of applications. Its combination of low equivalent series resistance, high temperature tolerance and high capacitance makes it an ideal choice for a variety of applications, ranging from communications to medical equipment.
