Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors feature a combination of energy storage, low price, and great form factor for many applications. The 35YXH270MEFC8X20 is one of the several types of capacitors used for specific tasks.

Overview

Aluminum electrolytic capacitors are polarized, the positive side is typically marked on the case. They are constructed of a solid aluminum anode in which is treated meeting the anodic oxide and, then, intruded with wound strips of electrolytic paper soaked in an electrolytic solution, acting as the cathode. The paper is then rolled and encased inside the anode with a dielectric composed of aluminum oxide. Finally, the capacitor is encased with an epoxy resin and metal sleeve.

35YXH270MEFC8X20 Application Field and Working Principle

The 35YXH270MEFC8X20 aluminum electrolytic capacitor is designed to be used in a power prototype application with an operating temperature range of -25 to 105°C and a rated ripple current of 1.35A (-55°C to +105°C). It typically has a rated voltage of 450V and a capacitance of 270µF. The 35YXH270MEFC8X20 aluminum electrolytic capacitor can provide a high degree of functionality and a great value.The aluminum electrolytic capacitor works by having the stored electric charge reside between the plates of the capacitor. As the voltage between these plates grows, the electrons move and store on the oppositely charged surface of the plates, such as on the metallic surface of the electrolyte. This creates the polarization of the capacitor through the dielectric property found in many materials such as paper or air. The capacitance of the 35YXH270MEFC8X20 aluminum electrolytic capacitor is quite high, due to its ability to store charges in between the plates. The larger the physical size of the capacitor, the greater its capacitance, as the larger surface area of the plates allows for more charge to be stored. This is especially true of aluminum electrolytic capacitors as the electrolytic dielectric used has a significantly higher dielectric constant compared to other types of dielectrics, meaning that much more charge can be stored. This makes aluminum electrolytic capacitors ideal for applications that require large amounts of charge to be stored in a small physical space, such as in cases of high capacitance.The combination of the aluminum electrolyte and the paper towel winding makes an effective and highly reliable form of capacitor that is inexpensive and convenient to use. Aluminum electrolytic capacitors have the unique ability to withstand harsh electrical environments and very high temperature ranges.

Conclusion

The advantages of the aluminum electrolytic capacitor are many. Its small physical size and low cost make it desirable for applications where space and cost savings are necessary. Its high capacitance and temperature range ensure that it can provide reliable protection for power prototypes. The 35YXH270MEFC8X20 is a great example of an aluminum electrolytic capacitor, and one of the many available.
