Aluminum electrolytic capacitors, also known as aluminum electrolyte capacitors, are polarized capacitors with a non-solid electrolytic type, which are commonly used for filtering and signal coupling in electronic circuits. This type of capacitor utilizes an electrolyte instead of a gas in its construction as the medium for electrical conduction. The main purpose of using an electrolyte in this manner is to increase the capacitance of the device, which can then be used for higher voltage ratings, higher current ratings and higher peak current ratings.The EEU-FC1V391B is a popular aluminum electrolytic capacitor. It is a long-life, high capacitance, low resistance, and large leakage current product. The EEU-FC1V391B has a capacitance range from 0.1µF to 1.0µF and a peak voltage rating from 10 to 65V. This capacitor can also withstand up to 10,000 hours of operation at -55°C to 105°C. The EEU-FC1V391B is used in a wide range of applications and serves the following purposes:High voltage DC/AC application: The EEU-FC1V391B is suitable for various voltage circuits such as audio amplifiers, video equipment, power supplies, and electronic equipment. It can be used as a coupling capacitor between the line and load in the DC/AC inverter systems, allowing low-frequency AC signals to pass through while suppressing high-frequency noise.Filter: The EEU-FC1V391B can be employed in noise filtering applications, specifically EMI/RFI reduction. This is especially useful for car audio systems, in which these caps can reduce interference from other electronic devices.Ripple current: EEU-FC1V391B is also used in applications where high ripple current is causing excessive fan noise. These capacitors reduce the ripple current thus creating better performance and longer fan life.Power converter and battery module: EEU-FC1V391B is an ideal capacitor for use in power converter and battery module applications, due to its low ESR and high ripple current capabilities. The basic working principle behind the EEU-FC1V391B is that, like other electrolytic capacitors, the capacitance is generated by the presence of an electrolyte between two metal plates. When the capacitor is connected to a voltage source, then a current flows and charges begin to accumulate on the plates. This creates a non-polarized electric field and due to the electrolyte, the capacitance values are typically much higher than for other types of capacitors. In conclusion, the EEU-FC1V391B is a versatile aluminum electrolytic capacitor used for various applications. It offers high capacitance, low ESR, high peak current rating, and long lifetimes, making it a suitable choice for a variety of applications.
