Tantalum capacitors, commonly referred to as tantalum electrolytic capacitors, are a type of electrolytic capacitor. They are capacitors that use tantalum as the anode material, with a polymer film forming the dielectric layer, and an electrolyte as the cathode, forming a three-layer structure. Compared with traditional aluminum electrolytic capacitors, tantulum capacitors have higher stability and reliability and narrower price range. They are widely used in power supplies, communication, computer, medical and scientific instruments, as well as other fields that demand high reliability and high frequency. Consequently, these types of capacitors have become indispensable in the fields of high-end technology applications.

CWR15FK225KCLC is one of these type of tantalum capacitors, which is widely used in high frequency fields. This product belongs to the surface mount type, with an operating temperature range of -55℃～+125℃ and a voltage rating of 150V. In addition, its maximum ripple current rating is 7.750A. This product is highly reliable and is used in extensive applications such as radio and television, mobile communication, communication networks, installations and other fields.

The working principle of CWR15FK225KCLC is based on the theory of electrostatic capacitance. Its working principle is that it uses a solid dielectric as the medium between its two electrodes, and forms a space charge layer on the surface of the dielectric, which stores energy in the form of a polarized electric field. Concretely, the electric field is generated when two metal layers of different electrical potentials (called electrodes) are placed near each other, the one with the higher electrical potential generates an electric field that penetrates the dielectric material, forming an excess of electrons in one electrode, and an insufficiency of electrons in the other.

When a voltage is applied across the two electrodes of CWR15FK225KCLC, charge flows from the electrode of higher potential to the one of lower potential, generating an electric field and causing displacement current through the dielectric. Then, the charge accumulates on the two electrodes, creating positive and negative charges, with an equilibrium formed due to the prevention of further charge flow through the dielectric by the electric field. In conclusion, the capacitor stores electric energy in the form of the electric field due to the displacement of electric charge between the two electrodes.

In conclusion, CWR15FK225KCLC belongs to the class of tantalum capacitors, which are used mainly in high frequency fields. It is characterized by its surface-mount type, a wide operating temperature range and an high ripple current rating. Its working principle is based on the theory of electrostatic capacitance. It works by generating an electric field and storage the electric energy between two electrodes, forming a polarized electric field and displacing charge between them.
