E91F401VSN391MR65T

Aluminum electrolytic capacitors are electrical components that store and release electrical energy. The E91F401VSN391MR65T aluminum electrolytic capacitor is an industrial grade model, and its use is primarily in high-frequency switching power supplies, DC-DC converters, and other related applications.

The E91F401VSN391MR65T features a non-polarized design, meaning it can be connected to an electrical circuit in either direction. It has a rated voltage of 400V and a capacitance of 391 mF. It has a wide operating temperature range of -40°C to +105°C, making it suitable for use in various industrial applications where there is likely to be an extreme environment.

The E91F401VSN391MR65T is also known for its low ESR, which stands for Equivalent Series Resistance. Low value ESR indicates that the capacitor will be more resistant to high frequency interference, and will also respond more quickly to changes in voltage or current. This makes it ideal for use in switching power supplies, where rapid changes in the voltage or current are common.

The working principle of aluminum electrolytic capacitors is fairly simple. It uses two aluminum plates that are separated by an electrolyte material. One plate is attached to the positive side of the electrical circuit, and the other is attached to the negative side. When a voltage is applied to the capacitor, ions in the electrolyte material are attracted to the plate with the opposite charge.

This causes electrons to move between the two plates and a charge to build up. This charge can then be used to store electrical energy, which is why aluminum electrolytic capacitors are often used in applications where energy storage and release are important.

The E91F401VSN391MR65T aluminum electrolytic capacitor is a reliable and robust model suitable for use in various industrial applications. Its high-frequency performance and wide operating temperature range make it ideal for use in switching power supplies, DC-DC converters, and other related applications.
