Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors (or aluminum electrolytic capacitors) are a type of capacitor, typically constructed from an anode, an anodized sheet or foil of aluminum, and a liquid or solid electrolyte. They are widely used in electronic circuits for various reasons, such as providing temporary surge and current capacity and providing feedback and inrush protection. They also have the advantage of providing stable voltage and very low stored energy.

The EKMS501VSN221MR45S is an aluminum electrolytic capacitor specifically designed for use in very low-noise, high-performance audio and other demanding applications. It is offered in three different sizes and is rated for a voltage range of 25 to 470 volts. It features an extended operating temperature range of -25 to +105°C and a maximum operating temperature range of +155°C. In addition, it has a total capacitance range of 0.001 µF to 10 µF with a capacitance tolerance of ±20%.

Application Field

The EKMS501VSN221MR45S aluminum electrolytic capacitor is suitable for a variety of very low-noise, high-performance audio, and demanding applications such as test and measurement systems, military and space, data processing, and medical. It is ideally suited for applications where high system accuracy is required, such as A/D and D/A converters.

Working Principle

The key to understanding aluminum electrolytic capacitors is how they are constructed. The aluminum foil is the anode of the capacitor and is coated with an insulating layer of aluminum oxide. Inside the capacitor, the aluminum oxide is saturated with electrolyte, and the electrolyte (which may be a liquid or gel) is separated from the anode and cathode by a separator. When an electric current is applied to the capacitor, current is conducted from the cathode to the anode through the electrolyte, creating a charge. This process is known as the “Faraday effect”. As the charge accumulates on the capacitor\'s plates, an electrostatic field is created and stored between them, holding the charge until it is discharged.

The EKMS501VSN221MR45S aluminum electrolytic capacitors are designed to provide excellent performance in high accuracy, low-noise applications. With their non-polarized design and high temperature ratings, they are well suited for use in high performance
