Tantalum Capacitors

Tantalum Capacitors, denoted by their reference code TR3D337K6R3C0100, are part of a family of capacitors used in electronics called the electrolytic capacitors. Its construction is a combination of a single piece of tantalum powder and two electrolytes that are typically made of manganese dioxide. The electrolyte acts as a capacitor’s dielectric, or insulating material, as it provides a layer of insulation between the capacitor’s electrodes. The construction of the capacitor allows for a very high energy density, providing a great amount of energy storage in a very small package.

Application Field

The tantalum capacitor\'s high capacitance, relatively low size and low cost makes it a great choice for various applications. It can be used as a digital signal processor, in electrical systems as an energy storage device and in analog devices. The capacitance of the tantalum capacitor is also very efficient, making it ideal for high-frequency applications. Additionally, due to its ability to be used in a variety of voltages, the tantalum capacitor is also a popular choice in applications that require an ability to withstand high-temperature operation.

Working Principle

The principle of operation of the tantalum capacitor is that two contacts, made of tantalum and the electrolyte, are separated by a dielectric. When a voltage is applied across the capacitor, the current flows through the capacitor in the same direction. This current creates a charge on one of the terminals, and as the charge increases, electrons start to flow from the other terminal, thus creating a current flow. This in turn produces a voltage, or a charge, across the capacitor. This charge will remain in the capacitor until the current is switched off, which allows for longer duration energy storage.

Tantalum Capacitors are versatile parts and can be used in many applications, providing high energy storage, great efficiency, and a robust construction.
