Aluminum Electrolytic Capacitors

UMF1V4R7MDD Application Field and Working Principle

Aluminum electrolytic capacitors, also known as electrolytic capacitors, are one type of the most commonly used capacitors around the world. This class of capacitors are unique because these are polarized production with a positive and negative contact, thus requiring installation with proper orientation. The “UMF1V4R7MDD” series of aluminum electrolytic capacitors are commercially sold by capacitor manufacturer companies and are used today in a wide variety of applications.

The series of UMF1V4R7MDD capacitors are of a non-solid aluminum electrolytic capacitors. This type of capacitors, have their insulating layer made of paper and are impregnated with electrolyte, a special kind of liquid that can condensate the electrical charges, providing the capacitance desired. This form of electrolytic capacitors provide larger capacitance than film or ceramic capacitors and are commonly used in power supply and coupling circuits for DC to AC conditioning.

The physical size and shape of the UMF1V4R7MDD capacitors make them ideally suited for applications where space is limited, such as computers, televisions, and automotive electronic systems. These electrolytic capacitors are smaller than other forms of capacitors and are not power-suppressor-class rated, making them a lightweight alternative for ease of installation.

UMF1V4R7MDD Working Principle

Through the application of a DC voltage to its points of contact, the UMF1V4R7MDD capacitors are able to store an electrical charge until it is released slowly at a time. The electrical charge stored in these aluminum electrolytic capacitors is analogues to a charge in an electric battery. This stored electrical charge is able to make a large contribution to the functioning of many electrical equipment and devices. These capacitors can be connected in series or parallel to achieve desired capacitance ratings and are often used in combination with other types of capacitors to improve their performance.

The way in which the UMF1V4R7MDD capacitor works is based on the principle of Faraday’s Law of electrolysis. This principle states that when a current is passed through an electrolyte (such as the electrolyte found in these capacitors), the various ions that are present in the electrolyte will move away from the area of current. This is what causes a charge to be stored in the capacitor, as the ions separate and an electric field is generated between the plates.

UMF1V4R7MDD Application Field

The UMF1V4R7MDD series of electrolytic capacitors are used in many forms of electronic equipment. These capacitors can be used in AC/DC power supplies, DC/DC converters, power supplies for computers, printers, LCD TVs, car stereos, audio amplifiers, defibrillators and other medical equipments, as well as high-end visual and audio recording equipments in studios. They are also used for signal-coupling and voltage-smoothing circuits, preventing voltage spikes from reaching sensitive electronic equipment.

Due to their encapsulated construction, these capacitors possess a high robustness and can operate in high temperature ranges (up to 105°C). Their ability to withstand long-term temperatures and frequent DC current have made them ideal for high-end audio and power supplies used in industrial and automotive applications where higher current handling is required.

Conclusion

The UMF1V4R7MDD series of Aluminum Electrolytic Capacitors have found widespread use across many industries. These capacitors are capable of offering a larger capacitance than film and ceramic capacitors, making them ideal for applications where space is limited. They can also operate in high temperature settings and in the presence of high DC current, making them very versatile and robust. The UMF1V4R7MDD series capacitors are used in power supplies, DC/DC converters, AC/DC power supplies, medical equipments, audio and recording equipments, and more.
