Tantalum capacitors are an important type of electrolytic capacitor, first developed in the early 1950s. These components are typically constructed with two electrodes - a tantalum metal anode, a conductive electrolyte as the cathode, and a dielectric oxide film between them.The CWR11HC226KB is a popular tantalum capacitor. It is a high-capacitance surface-mount component typically used for voltage-inverter applications and other basic circuit designs.The CWR11HC226KB has a typical working voltage of 2.5 Volts and is rated for a maximum back-bias voltage of 5.0V. Its anode and cathode terminals are environmentally treated for reliable connection and long-term reliability, eliminating oxidation and ensuring good electrical contacts for high-density installation. The package size of the CWR11HC226KB is 3.2x2.5mm.The main application field for the CWR11HC226KB are inverters, DC/DC converters, audio amplifiers, and other systems requiring a high capacitance, high voltage surface-mount capacitor. In these systems, the CWR11HC226KB is often used as an output capacitor in the power supply to ensure stable output, reduce ripple, and protect the system from electrical noise.The working principle of the CWR11HC226KB is a two-terminal, solid-state device that uses a capacitor as its main component. It consists of an anode (positive electrode), a cathode (negative electrode), and a dielectric oxide film between them. When a voltage is applied across the capacitor, a current is induced in the electrolyte and this current charges the capacitor and causes an electrostatic field to form inside it. When the potential is removed, the capacitor will retain its charge for some time, until it is discharged through its terminals.In conclusion, the CWR11HC226KB is a widely used, high-capacitance surface-mount capacitor suitable for use in inverters, DC/DC converters, audio amplifiers, and other systems requiring reliable voltage regulation. Its working principle is based on the charge and discharge of an internal capacitor, accomplished with a dielectric oxide film between two electrodes. Its key features include a working voltage of 2.5 V, environment-treated terminals, and a small package size of 3.2x2.5 mm.
