Aluminum Electrolytic Capacitors: LGY2A272MELB45 Application Field and Working PrincipleAluminum electrolytic capacitors come in various shapes and sizes, and these small devices play an integral role in many electric and electronic devices. One such capacitor type is the aluminum electrolytic capacitor, commonly designated as the LGY2A272MELB45. This capacitor is seen frequently in today’s powered consumer-end electronics such as computers, cellphones and digital cameras. Its unique characteristics make it the ideal choice for certain applications.Types of Aluminum Electrolytic CapacitorsAluminum electrolytic capacitors are classified according to their construction, and are available in two types. Polarized capacitors, such as the LGY2A272MELB45, contain an anode, or positive terminal, and a cathode, or negative terminal. Non-polarized capacitors, on the other hand, contain two positive terminals, but no negative terminal.The Construction of an LGY2A272MELB45The LGY2A272MELB45 aluminum electrolytic capacitor is a polarized type electrolytic capacitor. It has a diameter of 21.5 mm and a length of 42.5 mm. The capacitor is made of an aluminium foil as its anode, backed with a layer of paper as insulating material. The cathode of the LGY2A272MELB45 is an electrolyte with a manganese dioxide layer, providing the necessary anode current conduction. Features of LGY2A272MELB45The LGY2A272MELB45 capacitor has many features, which make it a popular choice in many electronic devices. It has a capacitance range of 10 to 1000 µF and a rated voltage range of 25 to 800 VDC. It also has a temperature range of -55 to +105°C and a very low equivalent series resistance. The construction of the LGY2A272MELB45 also enables it to deliver ripple current capabilities of up to 10mA. Furthermore, it has very low contact resistance and a low ESR.The Working Principle An aluminum electrolytic capacitor is a passive electrical component with a polarized electrical field. The electric field works on the principle of attraction and repulsion and gives rise to the phenomenon of capacitance. In a capacitor, the electric charge is stored in the form of an electric field, generated by an energy source. When a voltage is applied, it generates an electric field between the two plates of the capacitors. The electric field is created due to electrons being accumulated on one plate, forming a negative charge, while the other plate has a positive charge. As a result, the electric field created between the plates store the charge and allows the capacitor to be able to store energy.The Applications of an LGY2A272MELB45The LGY2A272MELB45 capacitor is used in many electric and electronic devices such as computers, cellphones, digital cameras and other electronic gadgets. It can be used in a number of applications such as signal rectification, filter circuits, voltage stabilization and power factor correction. With its low equivalent series resistance and high ripple current capabilities, it is also commonly used to filter out residual AC ripple currents from DC power supplies.ConclusionThe LGY2A272MELB45 aluminum electrolytic capacitor is unique in its characteristics, with its high capacitance range, low ESR, low contact resistance and temperature range of -55 to +105°C. It is capable of delivering up to 10mA of ripple current, and can be used in various applications such as signal rectification, filter circuits, voltage stabilization, and power factor correction. It is a very reliable and cost-effective capacitor that is ideal for many powered consumer electronics and electric and electronic devices.
