Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors belong to a type of polarized storage capacitors that use a semi-solid electrolyte. They are characterized by their large capacitance and extremely low equivalent series resistance (ESR). The UHE1E331MPT6 is an aluminum electrolytic capacitor that offers high capacitance values in compact sizes, making it ideal for applications such as power supplies, signal filters, decoupling, and energy storage. Here, we will discuss the application fields and working principle of the UHE1E331MPT6.

Application Fields

The UHE1E331MPT6 is an aluminum electrolytic capacitor designed for general use in electronic products. It is particularly suitable for use in power supplies, signal filters, decoupling, energy storage, and other high-density applications.In power supply applications, the UHE1E331MPT6 is capable of providing up to 4,000 hours of continuous operation at 105°C. This makes it suitable for use in many types of power supply designs, such as AC/DC adapters, DC/DC converters, UPS systems, and more.In signal filter applications, the UHE1E331MPT6 is able to achieve up to 550kHz of low-pass/band-pass filter cutoff frequency, making it suitable for a wide range of filters. The low ESR of the UHE1E331MPT6 also ensures that it can provide a stable, low-noise filtering performance.For decoupling applications, the UHE1E331MPT6\'s low ESR ensures that it can provide a sufficiently low source impedance to permit adequate DC blocking and prevent interference from leaking into the signal path. This makes it suitable for decoupling sensitive analog circuitry from power supply noise and transients.Finally, the UHE1E331MPT6 is capable of energy storage due to its large capacitance. This makes it suitable for applications such as light dimmer controls and power surge protection.

Working Principle

The UHE1E331MPT6 is an aluminum electrolytic capacitor that consists of a two-layer construction. The core of the capacitor is an aluminum foil that is etched and wound into an anode layer. This anode layer is then covered by a solid electrolyte layer and enclosed inside a cylinder-shaped casing.The inner anode layer is formed from aluminum foil that has a high specific surface area. This increases the effective capacitance and voltage of the capacitor. The anode is also etched, which creates microscopic pores in the surface area of the aluminum foil. This etching increases the surface area and allows the aluminum to be exposed to the electrolyte.The electrolyte layer of the UHE1E331MPT6 is typically a solid electrolyte such as manganese dioxide, which acts as both an electrode and an electrolyte. It functions as a current-carrying medium between the anode and the exterior of the capacitor. The electrolyte conducts ions from the anode layer into the electrolyte, allowing current to pass through the electrolyte. This current in turn creates an electrostatic field that stores energy in the capacitor.The UHE1E331MPT6\'s metal casing is designed to act as a Faraday shield, which prevents external electric fields from affecting the capacitor\'s stored energy. The casing also helps to contain any physical or chemical reactions that might occur within the capacitor.In summary, the UHE1E331MPT6 is an aluminum electrolytic capacitor designed for general use in electronic products. It is highly versatile, offering high capacitance values and low ESR in a compact size. The UHE1E331MPT6 is ideal for applications such as power supplies, signal filters, decoupling, and energy storage, and its working principle is based on a two-layer construction and an electrostatic field generated by a solid electrolyte.
