Aluminum electrolytic capacitors are capacitors that are used widely across communication networks, consumer applications, and in automotive and industrial uses. Part of the main function of these capacitors is to provide general network filtering and as a starting capacitor for electric motors. The EMVY160ADA470MF55G is an example of an aluminum electrolytic capacitor and its application field and working principle will be outlined in this article.

Construction of the EMVY160ADA470MF55G

The EMVY160ADA470MF55G is an aluminum electrolytic capacitor and constructed of aluminum, electrolytic film, and electrolyte. The capacitor’s construction starts with an anodized aluminum foil. The anode is then covered in a layer of metal oxide, followed by a porous separator or spacer. The metal oxide is made up of aluminum and other metals and this compound is usually referred to as a metalized film. The porous separator or spacer separates the metalized film from the electrolytic film. The electrolyte is then added into the porous separator or spacer.

The metalized film acts as the dielectric material and the electrolyte carries current to and from the terminals. The two components, the metalized film and the electrolyte, form what is known as an electrolytic cell that acts as a capacitor. The anode of the capacitor is the aluminum foil, the metalized film is the dielectric material, and the electrolyte is the cathode. This combination of components leads to the creation of a relatively high capacitance capacitor.

Application Field of the EMVY160ADA470MF55G

The EMVY160ADA470MF55G is designed for applications in communication networks, consumer applications, and in automotive and industrial uses. The capacitor’s wide capacitance range makes it particularly useful across a variety of applications including, but not limited to, general network filtering, starting capacitors for electric motors, high frequency buck converters, power supplies, and power line filter circuits.

The EMVY160ADA470MF55G is also used in RF and switching applications and is capable of withstanding high vibration and shock. In addition, the capacitor is UL recognized, temperature-stable, and halogen-free. The capacitor has a low ESL, making it ideal for high frequency applications. This makes the EMVY160ADA470MF55G a good choice for applications such as high frequency switching power supplies and DC-DC converters.

Working Principle of the EMVY160ADA470MF55G

The EMVY160ADA470MF55G works by utilizing the electrical characteristics of an electrolytic cell. This cell acts as a parallel plate capacitor with the anode being the aluminum foil and the cathode being the electrolyte. The capacitor’s design ensures that current can flow into the capacitor, but not out of it. When a voltage is applied across the anode and cathode, an electric field is created, inducing the electric charge onto the metalized film, the dielectric material. The dielectric material then stores the electric charge and a Separator or spacer prevents the transfer of the charge from one electrode to the other.

In summary, the EMVY160ADA470MF55G is an aluminum electrolytic capacitor used in many applications. Its wide capacitance range makes it useful for general network filtering, starting capacitors for electric motors, high frequency buck converters, power supplies, and power line filter circuits. It is characterized by having low ESL and being temperature-stable, UL recognized, and halogen-free. It works by utilizing the electrical characteristics of the electrolytic cell to store and transfer electric charge.
