Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are some of the most versatile and widely used capacitors available. They are available in a wide range of sizes and shapes, offering a variety of different capacitance values. They have a high capacitance to volume ratio, making them ideal for applications where space is limited, and their long life and high temperature stability make them a preferred choice in many applications.

EEU-FS0J272 is an aluminum electrolytic capacitor and is designed for small output voltage and low leakage current applications. It consists of a ceramic core with a crimp-on lead and an anodized aluminum case. It is rated for 65V and has a capacitance of 0.47uF at 10kHz. Due to its low rated ESR, it has high self-healing and low audio distortion. It is capable of handling high ripple currents and is ideal for use in audio and video applications.

Application Field and Working Principle

The EEU-FS0J272 aluminum electrolytic capacitor from Panasonic is designed to be used in audio and video applications such as amplifiers, equalizers, CD and DVD players, and digital video recorders. It is also suitable for use in medical equipment, telecommunication equipment and automotive applications.

The working principle of an aluminum electrolytic capacitor is based on the principle of electrolytic polarization. An electrolyte made up of a water solution of aluminum sulfate and an organic or inorganic acid is sandwiched between two electrodes (an anode and a cathode). A voltage is applied to the electrodes, and when the current passes through the electrolyte, an oxide layer "polarizes" on the surface of the anode and acts as a dielectric.

The oxide layer provides the capacitance of the capacitor and is the main factor in determining its capacitance value. The capacitance of the capacitor is affected by the size of the oxide layer, the thickness of the electrolyte, the applied voltage, and the temperature. Additionally, the capacitor is affected by aging, and its capacitance value decreases with time.

The EEU-FS0J272 aluminum electrolytic capacitor is available as standard with a terminal pitch of 6mm and a lifetime of 6000 hours. It is also specified for operation in temperature ranges of –25°C to +105°C. The capacitor has an operating temperature of 85°C, and an expected life of 2000 hours at that temperature. It has an effective series resistance of less than 0.1 ohm, and a low noise level.

The EEU-FS0J272 aluminum electrolytic capacitor from Panasonic is a reliable, cost-effective solution for audio and video applications. Its small size and low rated ESR make it ideal for use in applications where space is limited, and its long life and high temperature stability make it an ideal choice for applications where reliability is a must.
