Tantalum Capacitors

A tantalum capacitor is an electronic component, usually composed of two pieces of tantalum metal foil deposited on an oxide-coated metal electrode and covered in a plastic or ceramic case. This type of capacitor has the ability to store and release electrical energy, allowing it to be used in many different applications.

Tantalum capacitors are marked with the code "199D106X0035D2B1E3", which contains information about their device type, working electric fields, capacitance, and voltage rating. This code can be used to identify the exact type of capacitor for a particular application.

Application Field

Tantalum capacitors are mostly used in power supplies, filtering circuits, and signal processing applications. They provide high capacitance and low ESR in a small package size. They are widely used in computers, mobile phones, televisions, servers, and many other modern devices. Tantalum capacitors also find application in passive audio crossover networks, for high-end sound systems.

Tantalum capacitors are also used in automotive electronics, such as ECUs, switches, and driver assistance systems. Medical equipment, including X-ray machines and magnetic imaging systems, also use this type of capacitor.

Working Principle

Tantalum capacitors are utilized due to their high energy density and low leakage current. The principle of operation for the device is very straightforward. A layer of tantalum oxide, which acts as a dielectric, is deposited on a thin tantalum metal electrode. When a voltage is applied across the capacitors terminals, an electric field is created, causing the dielectric material to become polarized. This polarization stores energy in the form of an electric field, which then acts as a barrier between the two electrodes of the capacitor.

The Dielectric strength of the tantalum oxide film, combined with the high surface area of the electrodes, make the tantalum capacitor much more efficient than standard electrolytic or ceramic capacitors. This makes the device suitable for applications that require high capacitance in a small space. The device also requires very little current leakage, which makes it the preferred choice in applications that require very low resistance.

The ability of a tantalum capacitor to store electrical energy allows it to be used in many different types of applications. This makes the device a popular choice and increases its widespread use in the electronics industry.
