Tantalum Capacitors

Tantalum capacitors are widely used in many types of electronics application due to their unique electrical characteristics, excellent stability, and long life expectancy. CWR11KC475KB is a popular model of tantalum electrolytic capacitor, which is specifically designed to offer superior performance, reliability and stability in a variety of different electronic applications.

Applications of CWR11KC475KB

The CWR11KC475KB is an SMD capacitors with COTS (commercial-off-the-shelf) features, making it an ideal choice for a wide variety of military, aerospace, and industrial applications. CWR11KC475KB is typically used as a polar electrolytic capacitor, and can serve as a high-efficiency backup power supply when needed. Specifically, this capacitor type is suitable for filtering in radio-frequency receivers, as an output filter or a decoupling filter in DC-DC converters, and as a drive filter to stabilize the voltage and current of ICs and motors.

Working Principle of CWR11KC475KB

The working principle of any capacitor is based on the storage and release of electrical energy. The CWR11KC475KB uses an electrolyte and two metal electrodes to store and release electrical energy. The first electrode, the anode, is made from tantalum and is coated with an oxide layer. This develops an electrical potential of 1.3V-1.4V. This is connected to the negative terminal of the supply voltage. The second electrode is a cathode, which is made from either palladium or nickel. This is connected to the positive terminal of the supply voltage. When power is applied, electrons flow from the negative terminal to the anode, attracting ions to the opposite side of the capacitor. This creates an electric field and stores energy.When the power is disconnected, the ionic layer around the anode holds the energy and the electric charge begins to dissipate through the cation layer. This, in turn, releases the energy and the capacitor is fully discharged.

Advantages of CWR11KC475KB

The CWR11KC475KB is designed to be highly efficient, with a leakage current of less than 10 microamps. The oxide layer and anodic material provide high insulation, which makes it ideal for use in high-frequency applications and high temperature environments. The size and weight of the CWR11KC475KB is also very low, allowing it to be used where space is limited. Furthermore, it is highly reliable, with a long shelf life and low ESR.

Conclusion

CWR11KC475KB is a high quality, long lasting electrolytic capacitor that is used in a wide range of commercial, military and industrial applications. It offers excellent electrical characteristics, stability and a long life expectancy. The design of this model allows it to be used in environments where space is limited and in applications requiring high frequency and high temperature operation. Therefore, CWR11KC475KB is a valuable addition to countless types of electronic applications.
