Aluminum electrolytic capacitors were first introduced in 1934 and quickly gained favor as alternatives to the traditional paper capacitors due to their extremely low ESR, excellent frequency response, high capacitance, and comparably low price points. They are constructed using two rolled up aluminum foils, with a paper spacer in between and aluminum electrodes. The anode foil is usually folded to form a cylinder, while the cathode foil is wound in a coil. The metal foils are then soaked in a electrolyte solution and sealed in an aluminum case.

The ECE-A1EN470UB specifically is an 85°C, 105°C rated 105°C high ripple current, low impedance aluminum electrolytic capacitor. The dielectric is an aluminum oxide formed by an electrolytic action. Its anode core is composed of four rolled-up aluminum foil plates, and its cathode core is wound up in a coil, impregnated with an organic cell-friendly electrolyte.

The application field of the ECE-A1EN470UB includes power supplies, AC and DC inverters, AC motor controllers, DC electric drives, air-conditioners, welders, and many other electronic applications. It’s suitable for a variety of switching and smoothing circuits, and can be used to stabilise the voltage and current of power systems.

The working principle of the electrolytic capacitor follows the same principles as a regular capacitor, except that instead of using two conductive plates to store electrical energy, it uses a foam, or a sheet constructed from rolled up aluminum foil, along with an electrolyte solution to store the electrical charge. This electrolyte solution increases the capacitance by providing an additional pathway for electrons to flow through. When a voltage is applied to the terminals of the aluminum electrolytic capacitor, the electrolyte solution inside the capacitor breaks down and generates an electric field from the stored electrolyte charges, allowing for the charge to accumulate on the two metal plates.

The ECE-A1EN470UB aluminum electrolytic capacitor is widely used in electronic applications due to its high ripple current rating, low impedance, and reliable performance. The capacitor is designed with built-in self-healing features to help prevent shorts due to overvoltage or overload. Furthermore, it also offers excellent frequency response, so it can handle high currents without compromising the quality of the signal.

Overall, the ECE-A1EN470UB aluminum electrolytic capacitor provides reliable performance and superior durability for a variety of electronic applications. It is designed with built-in self-healing capabilities, making it a great choice for power supplies, AC and DC inverters, and more. Its excellent frequency response also ensures optimal signal quality in a wide range of conditions.
