Aluminum Electrolytic Capacitors—EKMH401VNN391MA40T Application field and Working Principle

Aluminum electrolytic capacitors are widely used in electronic equipment, electric instruments and communication devices, and can be used in many areas of electrical engineering. Among them, EKMH401VNN391MA40T aluminum electrolytic capacitors are commonly used and of high reliability.

EKMH401VNN391MA40T aluminum electrolytic capacitors are applied in the power system, audio equipment, automotive circuits, motor drive circuits and industrial device control systems, where they serve as energy storage, filtering effectiveness and help suppress electromagnetic interference (EMI). Their purpose can also be classified as time-constant circuits, frequency selection, noise suppression and DC voltage stabilization. In addition, EKMH401VNN391MA40T capacitors can store energy for quick discharging, which makes them suitable for handling high inrush current in motors and inverters.

EKMH401VNN391MA40T aluminum electrolytic capacitors operate on the principle of Faraday’s law. This means that a voltage applied across an electrolyte causes ions to move and form a charge on the two electrodes. The charged capacitors then produce a voltage that counteracts the original voltage. When a low external voltage or current is supplied, the capacitor discharges. With this, EKMH401VNN391MA40T capacitors can absorb and store energy that is later released as required, creating a cycle of charging and discharging. This scenario is repeated in many applications as discussed above.

EKMH401VNN391MA40T capacitors also feature the dielectric of Al2O3, also known as anodic oxide, which is sandwiched between two metallic plates. As the device heats, this dielectric expands and the plates contract, thus separating and reducing the capacitance. This capacitance varies depending on the value and voltage of the capacitor.

In order to guarantee an EKMH401VNN391MA40T aluminum electrolytic capacitor’s performance, certain parameters must be taken into account. Temperature rating is perhaps the most important, which is where the capacitors operate within specific temperatures without experiencing failure. Temperature range of -25°C to 85°C is usually acceptable for this type of capacitor.

The rated capacity of the capacitor is measured by the volume of electric charges stored and denoted by a unit called Farad. It is also important to determine the leakage current rating and the amount current discharged during operation, which is usually specified on the capacitor’s datasheet. Ripple current, which is the alternating current flowing through the device, is another key specification.

EKMH401VNN391MA40T aluminum electrolytic capacitor is an accurate, reliable and cost-effective device that can help provide stability, filtering and energy storage in a wide range of electrical applications. Its ability to store energy for quick discharging also makes it ideal for handling high inrush current in motors and inverters. Users need to take into account the parameters such as temperature range and ripple current when selecting an EKMH401VNN391MA40T aluminum electrolytic capacitor for their desired applications, to guarantee the device’s performance and longevity.
