Aluminum electrolytic capacitors are passive devices which store electrical energy. The EKMH800VND722MA45T is an Aluminum Electrolytic Capacitor designed for both low-leakage current (< 0.05μA @ 100Vdc) and high capacitance (850Vdc at 85℃). It is also known for its excellent stability and reliability.

The main component of the EKMH800VND722MA45T capacitor is a solid electrolyte, usually a polyphenylene sulfide (PPS) film. The aluminum housing of the capacitor is also filled with electrolyte. The aluminum foil electrodes are formed on the solid electrolyte and the aluminum housing. The cathode is constructed as an anode, and a thin layer of tantalum oxide, iridium oxide or ruthenium oxide is formed over the aluminum housing.

The typical application fields for the EKMH800VND722MA45T capacitor include applications requiring high capacitance density such as DC/DC converters, frequency synthesizers, and industrial motor drives. It is suitable for high frequency and high ripple applications such as power supplies for medical instruments, consumer electronics, and laboratory equipment. The capacitor’s high capacitance density, long life and reliability make it suitable for automotive, audio frequency, and space applications.

The working principle behind the EKMH800VND722MA45T capacitor is Electrolytic Double Layer Capacitance (EDLC). An EDLC device is made with a metal anode which interacts with the electrolyte. The current can only flow if the anode and electrolyte have the same electrical potential. When the voltage drops, the current flow stops and a double layer of charge is formed between the anode and electrolyte. This forms the electrolyte capacitor. When the voltage is increased, the charge is discharged and the circuit is recharged.

The EKMH800VND722MA45T capacitor exhibits high stable capacitance over an extensive range of temperatures. It has low impedance and low loss when operating in a high frequency range. The device is also resistant to high shock and vibration and is highly resilient to environmental stressors.

In conclusion, the EKMH800VND722MA45T Aluminum Electrolytic Capacitor is suitable for applications requiring high capacitance density and reliable performance. Its main component is a solid electrolyte film with aluminum foil electrodes, and its working principle is based on EDLC technology. The device provides high capacitance density, long life and reliability, and is suitable for high frequency and high ripple applications such as DC/DC converters and industrial motor drives.
