They are available in a variety of voltages including 16V, 25V, 35V, 50V, 100V, 200V, and 400V with a rated capacitance of 680µF. These capacitors have a high ripple current and a long life expectancy. They are ideal for applications where high voltage spikes are expected and a low equivalent series resistance (ESR) is required. It is suitable for applications such as snubber circuits, power supply filters, pulse power and boost transformers, large switching power supplies, communication equipment, and large motors.

Working Principle of LQR2W682MSEHBB

An aluminum electrolytic capacitor consists of aluminum foil, an oxide (aluminum) layer, and a liquid electrolyte. When a voltage is applied across the capacitor, an electric field is generated in the oxide layer, and the electric charge starts to accumulate. As the electric charge builds up, a current flows from one electrode to the other one. This current flow is limited by the effective series resistance (ESR) of the capacitor.

The liquid electrolyte serves as the medium between the two electrodes. It is typically a mixture of water and ethanol. This chemical mixture is capable of carrying electrical charge from one electrode to the other, while also acting as a dielectric material. This provides for more current capability without the need for larger physical size. The liquid also serves as a heat transfer medium, dispersing the heat generated by the capacitor.

The main advantage of aluminum electrolytic capacitors is their relatively large capacitance per unit volume. They are also capable of producing a relatively high current and can provide a low ESR. These properties make it ideal for use in power supplies and filtering circuits. Furthermore, they can be used for a wide variety of applications, including snubber circuits, rectifiers, and high frequency filters.

In conclusion, LQR2W682MSEHBB capacitors are reliable and durable components that can withstand extreme environmental conditions. They are suitable for a wide variety of applications, including power supplies, power factor correction, and filtering circuits. They offer a high capacitance per unit volume, can provide a high current, and have a low ESR. These capacitors are widely used in a variety of electronic circuits, making them an ideal choice for engineers.
