Tantalum Capacitors

299D225X0050CB6 Application Field and Working Principle

Tantalum capacitors belong to the family of polarized capacitors and are widely used for their lower profile, higher capacitance, and advanced energy storage and discharge capabilities. The 299D225X0050CB6 is a specific type of tantalum capacitor which is designed for low-voltage, moderate-power applications. It is typically used in audio amplifiers, computers, and signal processing equipment.

A tantalum capacitor contains two electrodes, also known as plates, made from tantalum metal. A thin insulating material separates these two plates and forms a dielectric between them. The two plates store an electrical charge, which creates an electric field between them. When a voltage is applied to the capacitor, the resulting electrical field can store energy in the form of a static electric field.

The electrical design of a tantalum capacitor is highly dependent on its size. The 299D225X0050CB6 has a radial construction, meaning that its two electrodes are arranged side-by-side in an annular shape. This particular type of capacitor has an extended temperature range of -55° C to +125° C. Its size measures 2.5mm in diameter by 5mm in height with a capacitance of 220μF and a working voltage of 6.3V.

The working principle and performance of a tantalum capacitor are dependent on its dielectric. The dielectric of a tantalum capacitor is typically formed from a ceramic material, such as manganese oxide, which is sandwiched between two tantalum plates. The manganese oxide helps to create a barrier between the two plates, allowing them to store and discharge energy. The thickness of the oxide layer can affect the performance of the capacitor, but each capacitor will have specific capacitance values and a specific working voltage.

The 299D225X0050CB6 is a popular type of tantalum capacitor due to its low profile and higher capacitance. It is designed for low-voltage, moderate-power applications, commonly used in audio amplifiers, computers, and other signal processing equipment. This specific tantalum capacitor is known for its extended temperature range, making it a reliable choice in extreme temperature environments.
