Tantalum Capacitors

A tantalum capacitor, is an electrolytic capacitor, a component of electronic circuits. It typically consists of two electrodes: an anode, made of tatanlum and a cathode often made of a metal oxide. The construction of the capacitor generally takes on a form similar to other electrolytic capacitors, such as aluminum electrolytic capacitors, but with the electrodes made from tantalum metal instead. This construction takes advantage of the fact that capacitors that use a metal oxide as the cathode are polar, meaning they have a positive and negative side. A tantalum capacitor is designed to act as a storage device for energy, allowing current to flow in and out of the device.

135D226X9075C2 Application Field and Working Principle

The 135D226X9075C2 tantalum capacitor is used in a variety of applications, especially in high-frequency circuits where a low profile and low parasitic element are required. They are commonly used in digital circuits, such as high-speed digital-to-analog converters (DACs) and dithering circuits. The working principle of the 135D226X9075C2 is similar to other tantalum capacitors. It consists of a tantalum anode and a metallic oxide cathode, and the oxide acts as an insulating layer. When a voltage is applied across the terminals, an electric field is created, causing a breakdown of the oxide layer and an electric current is generated.

The current passes through the oxide layer and charges the anode, forming a capacitor. The anode is charged to a level that is determined by the electric field strength and the voltage applied across the terminals. When current is passed through the capacitor, the voltage across the terminals changes, causing a distortion in the current. This process is known as electrical polarization and is responsible for the capacitance of the device.

The 135D226X9075C2 is available in various capacitance values, ranging from 2.2 to 220 microfarads, allowing it to be tailored to the needs of different applications. It is also capable of withstanding high voltages, up to 63 volts, and it has low equivalent series resistance (ESR). This makes it suitable for high-frequency applications, where low parasitic elements are essential.

In summary, the 135D226X9075C2 tantalum capacitor is a versatile component that is used in a variety of applications, particularly in high-frequency circuits. Its construction consists of a tantalum anode and a metallic oxide cathode, which when charged creates a capacitor. This device is available in various capacitance values, has a high voltage rating and a low ESR, which makes it suitable for high-frequency applications.
