Tantalum Capacitors

The tantalum capacitor, often referred to as a ‘tant cap\', is a type of electrolytic capacitor. It is constructed using a material such as tantalum, which is used as an anode, along with a cathode made of a different metal. The tantalum electrolyte acts as a dielectric, giving the capacitor its superior electronic properties. This type of capacitor is used widely in applications where higher operating voltages are required and where space efficiency is paramount.

299D475X0035CB6 Application Field and Working Principle

The 299D475X0035CB6 is a type of Tantalum capacitor, developed specifically to meet the requirements of modern electronics, particularly applications in the industrial and medical industries. The capacitor has a rated capacitance of 47μF, a rated working voltage of 10 VDC, and a temperature range of -40°C to +85°C. It is also AEC-Q200 qualified, making it suitable for a wide range of automotive applications.

The core component of the 299D475X0035CB6 is a thin sheet of tantalum, which is then sandwiched between two electrical contacts: a positive terminal known as the anode, and a negative terminal known as the cathode. When a voltage is applied between the terminals, an electrical current passes through the tantalum to form an electrolytic solution. This solution produces a faradaic reaction, whereby ions travel between the anode and the cathode, creating an electric charge on the capacitor.

This charge is stored within the capacitor as a form of electrical energy, known as ‘capacitance’. As a result, the capacitor functions as a form of energy buffer, as it can retain a charge for an extended period of time. This makes it an invaluable component in electronic circuitry, allowing it to provide short bursts of power during high-demand operations.

The 299D475X0035CB6 is constructed using a high-temperature, anodized tantalum core with manganese dioxide electrodes, providing it with an extremely high level of electrical resistance. This makes the capacitor ideal for applications where high performance and reliability are essential, such as in medical devices and industrial equipment. Additionally, the capacitor has a low impedance design, allowing it to quickly react to sudden changes in applied voltage. This is essential in applications such as voltage regulation, which require fast response times.

The 299D475X0035CB6 is also available in a range of different sizes and shapes, allowing it to be easily incorporated into a wide variety of different applications. Its relatively low cost and high-performance characteristics make it an ideal solution for a broad range of industrial, medical, and automotive requirements.
