Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are one of the most popular types of capacitors found in electronic devices. These capacitors are made of two thin aluminum foils, insulated by a thin layer of electrolyte, and are typically used in AC circuits. They are used to store electric charge and act as a filter or regulator to reduce ripple and ensure smooth delivery of current.The ECA-1HHG220 is a radial-lead aluminum electrolytic capacitor manufactured by Panasonic Corporation. Its rated capacitance is 220uF, with a wide operating temperature range (−25℃ to +105℃) and long-life performance. The voltage rating is 2.5V, making it suitable for the low-voltage circuit applications used in consumer electronic products and appliances.The construction of the ECA-1HHG220 consists of a sealed aluminum canister with two electrodes made of sintered metal and a polymer film. When electric current is passed through the canister, an electrolyte reaction occurs between the electrodes and the electrolyte inside, forming a film on the electrodes’ surface which serves as a dielectric. The canister also acts as a shield, helping to keep the electrolyte away from electric fields in the circuit.The working principle of the ECA-1HHG220 is based on the ability of the electrodes to store charge, which is then discharged when the current passes through it. This capacitance can vary depending on several factors, including the size of the canister and its internal dimensions, the composition of the anode and cathode film, and the type of electrolyte used. The higher the capacitance, the larger the charge storage capacity of the capacitor. The ECA-1HHG220 is primarily used in consumer electronics, such as television sets, radios, computers, etc. It is also used in various low-voltage circuits, such as DC voltage regulators, voltage-level shifters, and power supply circuits. The long-term stability and the wide operating temperature range make this type of capacitor ideal for these applications. In addition to being used as a passive filter, aluminum electrolytic capacitors can also be used for energy storage, such as in battery backup systems. This type of capacitor is typically designed for low-voltage applications, so it is not suitable for high-voltage applications.Aluminum electrolytic capacitors are widely used in all types of electronic circuit designs and have numerous advantages over other capacitors. They are easy to manufacture and offer efficient, reliable performance. The wide operating temperature range and long-term stability of the ECA-1HHG220 make it one of the most popular aluminum electrolytic capacitors on the market today.
