Tantalum capacitors are widely used in electronic equipment due to their excellent performance, reasonable price and good reliability. CWR26HC226JCGB/HR is a type of tantalum capacitors. This article first explains its application field, then introduces its working principle.

Application field

CWR26HC226JCGB/HR tantalum capacitors are most commonly used in the circuit of high-speed, high-frequency, high-power electronic devices such as computers, cell phones, and automotive electronics.   Its application fields also include military and aerospace fields, computers, cellular phones, telephone networking systems, industrial frequency control, DC-DC converter protection and so on. And because of its superior performance, it can usually be used in place of electrolytic capacitors.

Working principle

The CWR26HC226JCGB/HR tantalum capacitor is made up of the anode, the insulator of the anode, the electrolyte, and the cathode made up of carbon film. During the operation of the electronic device, the tantalum capacitor works in the form of a double-layer capacitor, in which the anode core of the tantalum capacitor acts as an anode, and the carbon film layer acts as a cathode. The two layers of electrodes form an electric double layer capacitor. This double layer capacitor can be charged and released when external voltage is applied and removed, thereby storing and releasing energy.

In addition, when a DC current passes through the tantalum capacitor, the anode core of the capacitance will be corroded, the leakage current increases, and the equivalent series resistance (ESR) will also be affected, and the capacitance values will change too. This phenomenon is called aging, and also affects the working performance of the tantalum capacitor.

In summary, CWR26HC226JCGB/HR tantalum capacitors are widely used in high-speed, high-frequency, high-power electronic equipment for their superior performance. The working principle of the tantalum capacitor is based on the electric double layer principle. In order to ensure its good working performance, it is necessary to pay attention to its aging and leakage during use, and reasonable parameter design.
