Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, commonly abbreviated as AEC, are a family of polarized capacitors where two aluminum plates are separated by a thin insulating layer of electrolytic material. They are one of the most widely used components in electronics. Compared to the more common ceramic capacitors and film capacitors, aluminum electrolytic capacitors have higher capacitance, larger voltage ratings, and longer service life. Moreover, their wide temperature range and low-ESR make them Particularly well adapted for use as energy storage device for high-frequency/high current electrical circuits. The EEE-HBC471UAP is one type of aluminum electrolytic capacitor from Panasonic. Designed for use in a wide variety of applications, the EEE-HBC471UAP features an extended temperature range of -55°C - +125°C, high reliability, and excellent capacitance stability over time. Its tighter tolerances and low-ESR makes it an especially ideal choice for motor control, dimming power supplies, and temperature measurement circuits. But what exactly is an aluminum electrolytic capacitor? Let’s take a look at the construction and working principles of this device. The EEE-HBC471UAP is an aluminum electrolytic capacitor housed in a compact package which is made up of three layers of components.The first layer is the aluminum cathode, where current enters the device. The second layer is the electrolyte which provides the electrical isolation. It is essentially a liquid dielectric that absorbs the electric charge, or energy, within the capacitor’s structure. The third layer is the aluminum anode, which releases the current from the device. Once energy has been absorbed, it is stored in the form of an electrical double-layer within the capacitor’s dielectric, created between the anode and the electrolyte. The electric double-layer causes an attraction, or polarization, of charges between the two metal plates. This polarization stores the electrical energy within the capacitor.When a voltage is applied across the device’s terminals, a “charge” is created and the capacitor begins to store the energy. The more voltage applied, the more energy is stored and the higher the capacitance value of the device. Aluminum electrolytic capacitors also have great electrical performance over a wide temperature range (-55°C to +125°C), due to the use of a special non-porous aluminum oxide (Al2O3) film as the dielectric. This film is formed when a voltage is applied to the device, chemicalizing the surface of the aluminum and forming an oxide layer that acts as an excellent electrical insulator. The EEE-HBC471UAP is a long-life and highly reliable aluminum electrolytic capacitor from Panasonic. Its longer service life and excellent stability over temperature make it an ideal choice for applications where reliability is paramount. Its tight tolerances and low-ESR make it a good fit for motor control, dimming power supplies, and temperature measurement circuits. Its small size, wide temperature range, and high capacitance make it a great choice for high-frequency/high current electrical circuits.
