Aluminum Electrolytic Capacitors, commonly known as “elecapacitors” are electrochemical devices utilized to store electrical energy. This versatile and ubiquitously used electrical component is present everywhere from electronic circuits to computer components, even to UV exposure monitoring systems in liquid chromatography. A version of such an electrolytic capacitor is the 515D478M025FR6AE3. In this article, the application field and working principles of this particular item shall be discussed.

The 515D478M025FR6AE3 is a Radial Lead Capacitors and measures in at 5mm in diameter and 12mm in length. With regards to capacitance, this elecapacitor furnishes a range of 47µF-1100µF. What sets this type of capacitor apart from the rest is that its voltage ratings can go up to 450V and its operating temperature can range from -55°C to +105 °C. As such, these capabilities make the 515D478M025FR6AE3 highly resistant to extreme temperatures and corrosion, as well as providing greater current and more capacitance than other capacitors.

The construction of the 515D478M025FR6AE3 contains several elements. The casing consists of four electrodes. An anode is suspended in a fluid by a diaphragm which is fabricated from a synthetic rubber. On the outside is the dielectric casing either constructed from solid aluminum or a thin etched foil called a “wet film.” Inside the casing is an electrolyte consisting of either an aqueous or solid solution. This is then filled with a gas, usually nitrogen, and the casing is hermetically sealed to the inner wall of the container.

The other components of the capacitor include a resistor connected to the anode and a diode connected between the anode and the cathode. This resistor helps control the current flow to the cathode while the diode helps to control the voltage that is present between the electrodes as well as preventing over-voltage or reverse current. The resistor, diode, and electrode make up what is termed “a compensation network” where the components are electrically equivalent, thus allowing for a constant current flow. This is important for maintaining the integrity of the capacitor.

The primary application field of the 515D478M025FR6AE3 are the consumer electronics industry. It is common for these capacitors to be used in high-frequency filter applications, such as DACs and DSPs, or as coupling capacitors for audio systems. They can also be found in mobile phones, digital cameras, and other communication devices. The capacitor is also used in industrial applications to condition currents, modify voltage levels, and provide temporary storage of electrical energy.

The working principle of 515D478M025FR6AE3 is based on electrolytic capacitor, which is a type of capacitor with electrolyte as one of its electrodes. It is constructed out of two electrodes; an anode constructed out of either solid aluminum or thin etched foil and a wet film covering the outside. The other electrode is a fluid-filled cathode made up of either aqueous or solid solution. When electricity passes through the electrolytic capacitor, the electrolyte inside it is converted into ions, creating an electric field between them.

The aluminum foil anode and the electrolytic solution form an “ionic solution”. This solution is constantly fed by electrical current, allowing for the formation of a double layer at the anode. The double layer forms a barrier between the outer wet film and the anode, preventing the exchange of current. The additional energy stored in the capacitor is proportional to the stored charge and the higher the voltage, the higher the energy stored. This energy can be used to supply current to various circuits and devices.

Overall, the 515D478M025FR6AE3 is a highly versatile elecapacitor used in a variety of electronic applications. It is built with robust construction and offers a wide range of voltage and temperature ratings. With the components and workings mentioned above, it is easy to see why the 515D478M025FR6AE3 is a common choice in consumer electronics, industrial applications, communications devices, and other electronic devices.
