Tantalum Capacitors

A tantalum capacitor is an electronic component made from the material of tantalum, which is typically used as a conductor and dielectric base. The main two components that make up a tantalum capacitor are the conductive layers and the dielectric layers. These layers are bonded together in order to facilitate the usage of a tantalum capacitor. Furthermore, the other main component is the electrolyte, which serves as a storage medium for the electrical energy that is being stored by the capacitor.

The 299D225X0050CB6E3 is a surface mount tantalum capacitor. It has a max operating temperature of 85°C and a capacitance of 22 uF. It is used with a voltage rating of 6.3 VDC and is 85°C rated. The package size is 5.3mm x 7.3mm making it a very small and compact part.

Application Field

The 299D225X0050CB6E3 is used in various fields due to its small form factor and high energy storage capabilities in relation to its size. This particular part is used for signal coupling and bypassing in audio applications, providing enough energy storage for a wide signal range. Furthermore, because it is temperature-resistant, it is also applied in various medical and robotic applications.

In addition, devices that require consistent power supply, such as DC/DC converters and power supplies, can find use for the 299D225X0050CB6E3. Its low ESR rating makes it ideal for devices that require stability and reliability in voltage power. High frequency power converters also find the 299D225X0050CB6E3 to be a highly reliable choice due to its high frequency characteristics and ability to store enough energy.

Working Principle

The working principle of a tantalum capacitor is relatively simple. First, a high-voltage circuit connects the surface of the tantalum to the positive side, while the other side connects to ground. This creates a large potential between the two surfaces. When the switch is closed, current flows into the capacitor causing a positive potential on the positive surface and a negative potential on the negative side.

As charge is supplied to a tantalum capacitor, two layers of electrical charges are formed on its surface. In the ideal case, these two layers are equal and opposite, meaning that one surface has an excess of electrons and the other surface has a deficiency. This creates a dielectric layer, which prevents current flow and thereby stores electrical energy.

The 299D225X0050CB6E3 works similar to other tantalum capacitors. It takes in charge, the connections to positive and negative potential supplies, and stores it in the form of an electrical field. This stored energy can then be used to drive current and store charge, and can be measured with a multimeter. Over time, the capacitors can lose some of their stored electrical energy, but typically only when subjected to extreme temperatures or vibration.

In conclusion, the 299D225X0050CB6E3 is a surface mount tantalum capacitor used for various applications. Its small form factor and temperature-resistant nature allow it to be used in various medical and robotic applications. Furthermore, its low ESR ratings make it highly reliable for varying voltages and high frequency power requirements. Its working principle consists of high-voltage circuit and charge being supplied to it, creating two layers of electrical charges that form a dielectric layer and store electrical energy.
