Tantalum capacitors are a type of capacitor with a tantalum cathode and an anode made of an oxide of tantalum with a large electrolytic capacitance in a small volume. The CWR11HH475KB is a tantalum capacitor that can be used in a wide range of applications, as well as having a wide range of size and voltage options. In this article, we will take a look at the application field and working principle of CWR11HH475KB.

The CWR11HH475KB is a polarized capacitor with a cylindrical-shaped housing. It has a capacitance of 475K and is rated for a working voltage of 11V, making it suitable for a wide range of applications such as power supplies, DC-DC converters, and automotive electronics. Its small size allows it to be used in circuits with space constraints, while its high capacitance makes it suitable for high power applications.

The CWR11HH475KB is a two-layer, two-pole capacitor. It consists of an anode foil and a cathode foil, both laminates in a cylindrical housing. The anode and cathode are separated by an oxide layer, which serves as the dielectric. Because the oxide is highly resistive, the capacitor effectively acts as an open circuit when a voltage is applied to the anode and cathode.

The working principle of the CWR11HH475KB can be explained with the help of a simplified equivalent circuit. When a voltage is applied to the anode, electrons flow from the anode to the oxide layer. This flow of electrons causes a current to flow in the circuit. As the electrons move through the oxide layer, they build up an electric field, which causes the capacitor to begin storing energy. This energy is then stored in the capacitor as a charge.

The amount of stored energy in the capacitor depends on the size of the capacitor and the applied voltage. As the applied voltage increases, the charge on the capacitor also increases. This increase in charge also increases the capacitance of the capacitor, meaning that more energy can be stored in the capacitor. When the applied voltage is decreased, the charge on the capacitor decreases and the capacitance of the capacitor decreases as well.

The CWR11HH475KB is a versatile tantalum capacitor that can be used in a wide range of applications due to its high capacitance in a small volume and its ability to withstand a wide range of voltages. Its two-layer construction, consisting of an anode foil and a cathode foil laminated in a cylindrical housing, allows it to store large amounts of energy in a small amount of space. Its working principle can be explained using a simplified equivalent circuit, and its capacitance is dependent on the applied voltage.
