04023J2R9CBWTR Working Principle

The 04023J2R9CBWTR thin film capacitors are composed of two or more electrodes separated by two thin layers of dielectric material. The two thin layers consist of a high-dielectric-constant material and a low-dielectric-constant material, creating a structure with a larger capacitance and higher leakage. When a DC voltage is applied to the 04023J2R9CBWTR thin film capacitor, a charge builds up on the capacitor’s terminals and it stores electrical energy. The capacitance of the 04023J2R9CBWTR thin film capacitor depends on the amount of energy stored on its electrodes and the dielectric constants of its thin layers. As the current through the device gradually dissipates, so does the energy on the capacitors’ electrodes. The 04023J2R9CBWTR thin film capacitors are mainly used for smoothing purposes, decoupling, and RV reduction in switching power supply applications. The internal resistance and imbalance of the electrodes, as well as the permittivity of the thin layers contribute to a wide range of impedance characteristics when the capacitor is operating in alternating current circuitry.

Conclusion

The 04023J2R9CBWTR is a high performance, reliable thin film capacitor that has been designed for applications in power supplies and control systems. Thin film capacitors such as the 04023J2R9CBWTR offer a wide range of electrical and physical properties that result in a product that is capable of providing reliable storage of electrical energy even in high power applications. The 04023J2R9CBWTR thin film capacitor\'s stability and flexibility ensure a dependable performance across a wide range of utilization areas making it a perfect solution for electronic and electrical equipment.
