Aluminum Electrolytic Capacitors

Aluminum Electrolytic Capacitors (AECs) are some of the most commonly used capacitors in the electronics field. They have wide range applications and are favored for their very low equivalent series resistance (ESR) and long-term reliability. They are widely used in switching power supplies, pulse circuits, filter circuits, signal processing and timing circuits, and resonant circuits. In capacitor technology, ECO-S1KP472CA is one of the most commonly used aluminum electrolytic capacitors. The ECO-S1KP472CA is a radial-type aluminum electrolytic capacitor with a 105°C long-life designed and is suitable for applications that require high stability and long life. Its rated capacitance range is 47μF~470μF and its rated voltage range is 10V~63V.The ECO-S1KP472CA application field and working principle can be summarized as follows：

Application Field

ECO-S1KP472CA is primarily used for DC filtering applications, such as power supplies and audio-frequency circuits. The device can also be used for charging and discharging operations in snubber circuits and resonant circuits.

Working Principle

ECO-S1KP472CA capacitor is based on the principle of electrolytic capacitors. Its operating principle involves two structures: an anode and a cathode. In the electrolytic capacitor, the anode is made of an aluminum foil with an oxide film. The cathode is composed of a thin alumina paper impregnated with a conductive polymer. The electrolytic capacitor functions by passing an electrical current through the aluminum foil, which creates an electric field across the oxide film and the alumina paper. The electric field creates a space charge which stores the electric energy. When the current stops flowing, the electric field is released and the energy stored in the capacitor is released.ECO-S1KP472CA is built with a large capacity and offers excellent capacitance stability and ripple current capacity. The capacitor also has very low equivalent series resistance (ESR) which is extremely important in dealing with the high-frequency ripple current seen in power supplies. Additionally, ECO-S1KP472CA capacitors are designed for a long life and feature a 105°C long-life rating and an improved thermal endurance.In conclusion, ECO-S1KP472CA aluminum electrolytic capacitor is designed for a variety of applications. Its low ESR, long-term reliability, and high ripple current capacity make it an ideal choice for DC filtering and many other circuits. This type of capacitor is also highly recommended for power supplies, snubber circuits, and resonant circuits due to its long-term reliability and excellent thermal endurance.
