Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a type of capacitor that uses an anode of electrolytic aluminum foil, a dielectric of oxide film, and a liquid or solid electrolyte as a cathode. These capacitors have a very large capacitance value, high ripple current capability, and low leakage current. The EEU-FC1E221 is an aluminum electrolytic capacitor that is manufactured by Panasonic Industrial Devices.

EEU-FC1E221 Application Field and Working Principle

The EEU-FC1E221 is well suited for power supplies and can be used in a wide variety of applications from consumer electronics to industrial automation. Its rated voltage is 6.3V, and it has a wide temperature range of -25°C to 85°C. In terms of its construction, the EEU-FC1E221 consists of an anode sheet of electrolytic aluminum foil, a dielectric of oxide film, and a liquid electrolyte as a cathode. The anode sheet and dielectric are separated by a thick liquid electrolyte. The capacitance is determined by the length and area of the anode sheet and by the thickness of the dielectric.

The working principle of the EEU-FC1E221 capacitor is based on the electric field formed between the two electrodes. The anode and cathode of the capacitor form an electric field when a voltage is applied to the terminals. The electric field causes the ions of the electrolyte to move toward the anode, creating a charge on it. This charge accumulates until it builds up enough to oppose the applied voltage, resulting in a decrease in current flow. The current is then stored in the capacitor as energy. The capacitor is then able to discharge this energy when a load is connected to its terminals. This process is known as capacitance.

The EEU-FC1E221 has several advantages over other types of capacitors. It has a low equivalent series resistance (ESR) and a high ripple current capability. This makes it ideal for high-frequency applications such as power supplies. Additionally, it has a long life span due to its oxide dielectric that is impervious to aging. As such, the EEU-FC1E221 can be used in applications where reliability and long-term performance are desired.

In conclusion, the EEU-FC1E221 aluminum electrolytic capacitor is an ideal choice for a wide range of applications due to its high capacitance value, low ESR, and high ripple current capability. Additionally, its long life span and low leakage current make it an excellent choice for applications where reliability and performance are required. Its suitability for high-frequency applications and its wide temperature range make it an ideal choice for many applications.
