Aluminum Electrolytic Capacitors: EEU-FC1H180H Application Field and Working Principle Aluminum electrolytic capacitors are the most common type of capacitor and are widely used in various applications. The EEU-FC1H180H is an aluminum electrolytic capacitor that belongs to the wide family of aluminum capacitors. This article will explore the application fields and working principle of this specific type of capacitor.Application FieldThe application field of aluminum electrolytic capacitors is quite broad and encompasses a wide variety of components. For example, the EEU-FC1H180H is used in high-voltage switching DC-DC converters and power drivers for optical communication devices. It is also commonly used in signal-processing systems such as audio amplifiers, audio preamplifiers, and audio power supplies. In addition, it is often encountered in AC adapters and power supplies for portable devices such as cameras, cell phones, and laptops. The EEU-FC1H180H also has a wide application in consumer electronics, including television and monitor power supplies, motor drives and robotics, automotive electric power systems, aircraft systems, and telecommunications power systems.Working PrincipleAn aluminum electrolytic capacitor is composed of two electrodes separated by an electrolyte. The anode is a piece of anodized aluminum, and the cathode is usually a wet cloth soaked in a liquid electrolyte.When a voltage is applied to the capacitor, the anode polarizes and ions from the electrolyte accumulate on its surface. The ions are attracted to the cathode, forming an electric double-layer. This electric double-layer creates an electric field that can store electrical energy. The EEU-FC1H180H is also designed with an internal safety element to limit voltage difference across the capacitor. This kind of capacitor also has an impedance of a certain frequency range and ensures the larger capacitance than other aluminum electrolytic capacitors of the same size. In addition, the EEU-FC1H180H has a relatively large capacity and can handle high ripple currents. It is also resistant to voltage spikes and is highly stable over time and temperature. ConclusionIn conclusion, the EEU-FC1H180H is a versatile aluminum electrolytic capacitor that has a wide range of applications in the consumer electronics industry and other fields. Furthermore, its working principle relies on electric double-layer formed by ions accumulating on the anode and being attracted to the cathode. The various characteristics of this capacitor make it suitable for a range of different applications.
