SN220M050ST Datasheet/PDFAluminum Electrolytic Capacitors
Aluminum electrolytic capacitors are polarized capacitors that use an electrolyte to achieve their storage of energy in an electric field. They are widely used due to their low cost and small size relative to other types of capacitors. This makes them ideal for use in electronic circuits, where they can filter high frequency signals, damp out power supply ripple, and provide bypassing. Aluminum electrolytic capacitors are constructed of two layers of aluminum foil that are separated by a layer of paper or other insulating material. The anode is the thinner foil, while the cathode is the thicker foil, and electrode pairs are connected together with a fluid called electrolyte. The electrolyte provides ion motion between the electrodes, allowing electric energy to be stored capacitively.
SN220M050ST Application Field and Working Principle
The SN220M050ST is an aluminum electrolytic capacitor rated at 50V with a capacitance of 220 μF, and it is designed for use in a wide range of applications, including signal processing, audio amplifiers, and power supplies. It features a performance of 7.8mΩ, low ESR, and high ripple current capabilities, which is suited for types of pulse load applications. In terms of applications, the SN220M050ST can be used in power supplies and voltage regulation circuits, as well as signal filtering.
The SN220M050ST\'s working principle is the same as all aluminum electrolytic capacitors. The capacitor has two electrodes which are separated by a layer of paper or other insulating material and filled with electrolyte. When voltage is applied to the capacitor, ions in the electrolyte move between the electrodes, creating an electric field. This electric field stores electrical energy in the capacitor, and this stored energy can be released when the current in the circuit changes, such as when a pulse of current is provided to the circuit.
The SN220M050ST\'s main feature is its high ripple current capability, meaning that it is capable of handling high frequency signals with little or no distortion. This makes the component ideal for use in audio amplifiers and signal processing applications. Additionally, the capacitor\'s low ESR rating and good dissipation factor also make it a useful component for use in power supply and voltage regulation circuits.
In summary, the SN220M050ST aluminum electrolytic capacitor is a high-performance component that can be used in a wide range of applications, including signal processing, audio amplifiers, and power supplies. Its main features are its high ripple current capability, low ESR, and good dissipation factor, making it a great choice for use in all sorts of pulsed load applications.
