Aluminum Electrolytic Capacitors have been widely used in a wide range of electrical and electronic applications. They are mainly used for coupling and bypassing, AC power filtering, energy storage, and rapid discharge. UPM2A4R7MED1TA is one type on Aluminum Electrolytic Capacitors with the characteristics such as very low equivalent series resistance (ESR), excellent frequency characteristics, and high ripple current capability.These capacitors are more reliable and robust than other capacitors. The component of the aluminum electrolytic capacitor is aluminum foil with a thin layer of an oxide layer is coated on one side. This oxide layer works as the dielectric material and has high-value permittivity of 150 or more. The other side of the aluminum foil is etched to increase the surface area. Then the aluminum foil is rolled with the electrolyte material soaked in optimized paper and rolled with the aluminum foil which is a key to ensuring high-volume capacity.

Working Principle

It works on the principle of the electrolyte, the oxidized aluminum and the anode, where the capacitance is created by charging the anode and cathode with opposite charges. The dielectric material between the two plates is the oxide layer on the anode. When the voltage is applied between the anode and cathode of the capacitor, a layer of oxide is formed on the surface of the anode and the capacitor is charged. The thickness of this oxide layer will then determine the capacitance.

Application Field

UPM2A4R7MED1TA can be widely used in bypassing, AC power filtering, high-energy storage applications, and rapid discharge for all kinds of industrial automation, communications systems, medical and computer/network system design and other electronic systems to provide high energy density output. For example, it can be used in power electronic designs in which the device is used in dc/dc converters, full-wave rectifiers, resonant AC/DC converters and chopper circuits. In other power systems such as AC /DC converters, IP based power supply units, DC motor drive, HVAC systems, and special purpose electric vehicles, UPM2A4R7MED1TA provides both robustness and flexibility. In addition, being one of the most compact styles of aluminum electrolytic capacitor, UPM2A4R7MED1TA is also an ideal component for many high-frequency power electronics systems including microwave transceivers, switching regulators, and resonant converters, as its self-healing feature, its ability to achieve huge capacitance in very small space, make them the ideal choice in applications where the highest level of energy efficiency is required.In summary, UPM2A4R7MED1TA is a type of aluminum electrolytic capacitor with excellent characteristics such as very low equivalent series resistance (ESR), excellent frequency characteristics, high ripple current capability and self-healing feature. It can be used in an extensive range of application fields, from power electronics designs, AC/DC converters, IP based power supply units, DC motor drive, HVAC systems, special purpose electric vehicles, microwave transceivers, to switching regulators and resonant converters.
