Aluminum - Polymer Capacitors

10SEPC270MD+S capacitors are a type of aluminum - polymer capacitor. They combine long life with low profile construction. They are ideal for use in applications that require relatively low leakage current, fixed capacitance, and wide temperature range stability. They are also used in military, aerospace, medical, and commercial applications.

Applications

10SEPC270MD+S capacitors are well suited for use in applications requiring high capacitance stability at temperatures from -55°C to 105°C. Typical applications include bypass, decoupling, and filtering in power electronic circuits. They can also be used to form impedance-matching networks for noise filtering of switch-mode power supplies, data lines, and wireless transceivers.

The 10SEPC270MD+S capacitors have excellent frequency range characteristics and stability, making them suitable for high speed signal processing applications. They can be used in frequency synchronization circuits, RF signal conditioning and filtering, wideband couplers, and signal presence detection.

Working Principle

10SEPC270MD+S capacitors are a multi-layer ceramic type aluminum-polymer capacitor. This capacitor design typically includes multiple sheets of ceramic layers, which are interspaced with a thin layer of aluminum electrolyte. This configuration creates a high capacitance value for the capacitor in a very small physical package.

In the capacitors, electric charge is stored in the capacitor plates in the form of charge densities. The number of electric field lines and the amount of charge density stored in the capacitor will determine the total capacitance. The charge density is stored and redistributed on the dielectric material, which separates the two plates. When a voltage is applied to the capacitor plates, the free electrons jump between the capacitor plates and create an electric current. This flow of electrons creates a magnetic field which causes a change in the voltage on the plates of the capacitor. This change in voltage is what affects the capacitance of the capacitor.

10SEPC270MD+S capacitors are widely used in power electronics and high-speed signal processing applications. Since the capacitors have a very low profile and can be used over large temperature ranges, they are the ideal choice for applications requiring small form factors and high reliability.
