<p>T55T476M004C0070 is a type of tantalum-polymer capacitors, which is one of the most popular capacitors available in the market today. These capacitors have been around since the late 1970s and are widely used in a variety of applications. The capacitance of T55T476M004C0070 is 47µF, with a rated voltage of 4V, and a tolerance of ±20%. The temperature range of operation is -55°C to +85°C.</p><p>Tantalum-polymer capacitors are a type of electrolytic capacitors, consisting of a positive and negative electrode separated by a thin layer of electrolyte. They are constructed with a manganese dioxide electrolyte, which serves as the dielectric between the two electrodes. The positive electrode is made from a layer of electrolyte and a layer of tantalum, which provides for good conductivity and a high capacitance. The negative electrode is then made from a layer of polymer.</p><p>The major advantage of a tantalum-polymer capacitor over traditional electrolytic capacitors is its robustness. The tantalum-polymer capacitor is much more resistant to shock, vibration and extreme temperatures, making it ideal for applications where high performance and durability are desired. In addition, the tantalum-polymer capacitor is less costly than other types of electrolytic capacitors, making it more attractive to manufacturers.</p><p>The working principle of a tantalum-polymer capacitor is relatively straightforward. When a voltage is applied across the two electrodes, an electrical field forms, resulting in the storage of electrical charge within the capacitor. This stored charge is then released when the current is cut off, providing the desired electrical output.</p><p>The main application field for T55T476M004C0070 capacitors include power electronics, automotive, aerospace, medical, and military applications. In each of these fields, the performance and reliability of the capacitor is of utmost importance. For example, in automotive systems, the capacitor must be able to withstand high temperature, moisture and vibration levels without failing. In the aerospace field, the capacitor needs to be able to provide high performance over a wide range of temperatures, providing reliable power to critical systems such as navigation and communications. In medical applications, the capacitors are used for implantable devices, defibrillators and other medical instruments, and must be able to provide reliable power to the delicate electronic components used in such devices.</p><p>Tantalum-polymer capacitors, such as the T55T476M004C0070, are an excellent choice for applications requiring wide temperature ranges, high reliability, and robust performance. With the right selection of capacitors, manufacturers can achieve maximum efficiency and performance in their products.</p>
