Aluminum Electrolytic Capacitors, commonly known as ‘cap’ for short, are electric components with a wide range of uses today. An aluminum electrolytic capacitor is a type of electric double layer capacitor (EDLC), which is composed of an electrolyte, electrode and separator. It is usually used in electronic equipment due to its feature of providing large capacitance values within a limited volume.EEV-FK1C221P is known for its high capacitance values and durability to environmental influences. The part belongs to the snap-in series, making installation faster and easier. It is a non-solid electrolyte aluminum capacitor with a very low ESR and ESL. The internals of EEV-FK1C221P consist of a conductive aluminum foil and two electrolytic layers. The cylindrical anode consists of a conductive oxide film developed on its internal surface. The capacitor is designed for all surface mounted equipment requiring a long life storage or signal capacity high-efficiency de-coupling applications.The application field and working principle of the EEV-FK1C221P can be further explained through a simplified example. Imagine that we have connected a voltage source to this capacitor via two pins. When we turn on the source, electrons will start flowing through the circuit, providing a path of conductance for the electric current. With the introduction of the capacitor, due to its non-polar nature, an electric field starts to build up and forces the electrons to disperse into the anode and cathode of the capacitor. This is due to the capacitance value of the capacitor which determines the amount of charge carriers need to be supplied for maintaining the same potential difference across its plates.The charge carriers (electrons) cause a polarization of the anode and cathode, creating two capacitance paths between the two plates. The charge movement through the capacitor is known as leak current. This phenomenon of electrical charge and discharge is responsible for the leakage of current across the capacitor. The capacitance of the EEV-FK1C221P can be further adjusted by varying the number of charge carriers or by changing the dielectric constant of the material. This dynamic allows the capacitor to be used in a variety of applications such as power factor correction, energy storage, signal filtering, or AC line filtering.The life expectancy of the EEV-FK1C221P also greatly depends on the environment. Its lifetime is mainly determined by the storage system temperatures, load current, ripple current and reverse voltage. In order to ensure the best performance and safe use of this capacitor, its environment must be kept at a lower temperature with low load current, surge current and reverse voltage. The capacitor is also designed to be more resistant to acidic solvents, hydrocarbons, and exposure to temperatures of up to 200°C.In conclusion, the EEV-FK1C221P aluminum electrolytic capacitor is designed for high efficiency de-coupling applications suitable for a variety of applications. Its features such as small size, high maximum capacitance values, and long life expectancy make it an ideal choice for use in a variety of applications. Its non-solid electrolyte and no inclusion of lead make it one of the most popular and widely used capacitor types in the market today.
