Aluminum electrolytic capacitors are a type of polarized capacitor with an electrolytic anode material which uses a non-solid electrolyte to store electric energy. They often come in very small sizes and provide good stability and lower ESR. The EKMQ630ELL470MF11D is a popular aluminum electrolytic capacitor designed to fit into certain electronic equipment.

The EKMQ630ELL470MF11D has a solid aluminum body and features a common technical nominal voltage rating of 6.3 VDC, a linear capacitance value of 470 μF with a power rating of 11D. A standard operating temperature range for the component is from -25 to 85°C. It is commonly available in a package size of 8mm x 11.5mm.

EKMQ630ELL470MF11D capacitors can be found in many types of electronic equipment such as DVD players, laptop computers, sound systems, power supplies, and many other consumer electronic devices. These types of capacitors are found in many electronic circuits that use a good combination of high capacitance and low impedance.

The Working Principle of the EKMQ630ELL470MF11D

The functioning of the EKMQ630ELL470MF11D aluminum electrolytic capacitor involves a polarized electrolytic anode consisting of a layer of highly porous anodic aluminum oxide film deposited onto foil of pure aluminum. Inside the capacitor are two metallic plates made of aluminum, with a non-solid electrolyte between them.

At the anode side, the electrolyte acts as an insulator, while at the cathode side, the electrolyte acts as a conductor. When a DC voltage is applied between the two plates, current starts flowing in the electrolyte and the capacitor starts charging. The electric charge stored in the capacitor between the two plates is proportional to the voltage applied.

In the EKMQ630ELL470MF11D, a capacitor formed by the two plates and electrolyte is connected in series with a series resistor which limits the peak inrush current. This resistor tames the current inrush to the capacitor and limits stress on the internal components and the capacitor itself. The resistor also prevents the capacitor from discharging at an uncontrolled rate.

The EKMQ630ELL470MF11D has its main uses in voltage regulation, energy storage and filtering of electrical signals, as well as providing peak current during the start up of equipment, protecting against line voltage variances, and helping avoid surges. The capacitor is also ideal for use in both filtering applications and for enhancing the performance of power supplies.
