Tantalum Capacitors

Tantalum capacitors are typically categorized as small and medium sized aluminum electrolytic capacitor. These components are used in all types of electronics, from computer boards to audio equipment. They are commonly used in high end audio systems, as they provide a more consistent sound quality and frequency response. In addition, they are excellent for reducing EMI interference because of their relatively low ESR. Tantalum capacitors are often made from a mixture of tantalum, oxide, and polyester (PEN).

The 152D226X0050R2B-variant of the tantalum capacitor is a radial-leaded, surface mount device that is relatively small in size and is commonly used in applications that require high levels of reliability and performance. The most common applications include: portable electronics and consumer products, automotive, and medical equipment. The device is also suitable for use in industrial or military settings where high environmental conditions and temperatures may be present.

Examples of common applications include: automotive and signal circuit filter, audio processors, decoupling and power supply filtering, voltage regulation, bypass, coupling, energy storage, and military aviation systems.

152D226X0050R2B Working Principle

Tantalum capacitors are capacitors consisting of two thin layers of tantalum that are separated by a layer of oxide. The outer layer is a semiconductor oxide, while the inner layer is a conductor, such as tantalum pentoxide (Ta2O5), which acts as a dielectric to electrically insulate the two layers. A charge can be stored in the capacitor by charging the inner layer, resulting in a voltage across the two layers.

The capacitor acts as an electric reservoir, capable of storing an electrical energy and releasing it when necessary. The 152D226X0050R2B variant of the tantalum capacitor is able to withstand a wide range of environmental conditions due to its advanced construction and features. It can be used in extreme temperatures from -55°C to +125°C, and exhibits low impedance performance and temperature cycling to ensure long life performance in high temperature applications.

The 152D226X0050R2B capacitors feature excellent volumetric efficiency and high capacitance density. This allows them to be used in larger capacitance values than other types of conventional capacitors, with maximum capacitance values up to 154μF. With a wide range of capacitance, temperature ratings, and operating voltages, these capacitors can be used in a variety of applications.
