Tantalum-Polymer Capacitors Overview

Tantalum-Polymer capacitors are an important family of surface mount capacitors, serving many applications in the electronics industry. They are different from common ceramic capacitors because, although they generally cost less, they pack the same amount of energy storage, and are much smaller in size and weight. A tantalum-polymer capacitor, for example, would typically be about one tenth the size of a standard ceramic capacitor offering the same capacitance.This makes them ideal for use in a variety of electronic products, including medical, military, aerospace, and high-end consumer applications. They have become increasingly popular as the demand for small, efficient, and low-cost components has grown.The T551B147M006AH capacitor is a part of the tantalum-polymer family, and it is specifically designed for military and high reliability applications. It has a capacitance of 0.047 uF, a voltage rating of 6 volts, an insulation resistance value of 25,000 MOhm, and a dielectric withstanding voltage of 12 volts. The operating temperature range is -55 to +125 Degrees Celsius.

Tantalum-Polymer Capacitor Working Principle

Tantalum-polymer capacitors, as their name implies, use a combination of tantalum and a type of organic polymer as part of their construction. The tantalum material is used to form the electrode plates of the device, while the polymer acts as a dielectric between the electrodes, allowing it to store and release energy. At the heart of the capacitor is a series of alternative layers of metal and organic polymer material which are created in a process called electrodeposition. In this process, a thin layer of metal (usually tantalum or niobium) is electroplated onto the organic polymer material. This process is repeated many times until the desired thickness is reached, usually a few hundredths of a millimeter. The result is a capacitor that consists of many layers of metal and polymer, all sandwiched between two electrodes.These multiple layers act as energy storage mediums. As current passes through the capacitor, a voltage is created on the layers of the dielectric material. This voltage is stored in the capacitor and can remain there until a voltage of opposite polarity is applied to it. It is this property of capacitors that makes them so useful in electronic circuits - they can store energy, and then release it when needed. One of the main advantages of a tantalum-polymer capacitor is that it has a higher dielectric strength than many other types of capacitors. This means it can handle its rated voltage without being damaged or degraded. It is also more resistant to corrosion as the tantalum materials used are less prone to oxidation. It has a lower ESR than many other types of capacitors and will also operate over a wider temperature range.
