Aluminum Electrolytic Capacitors are a type of capacitor with a large capacitance in a relatively small size. They are especially well-suited for AC applications that require a low equivalent series resistance. 400AX15MEFC10X16 is a popular type of aluminum electrolytic capacitor. In this article, the application fields and working principles of 400AX15MEFC10X16 will be discussed.

Application Fields of 400AX15MEFC10X16
400AX15MEFC10X16 is commonly used as decoupling capacitors in AC/DC circuits. It is often used on the AC side of a DC/DC power supply to reduce the inrush current and filter the output ripple before it reaches the load. It’s also often used on the DC side of the DC/DC power supply to reduce the output ripple and improve the Quieting effect. It’s also used in various motor switch, low-pass filter, resonant circuit and high current rectifier circuit applications.

Working Principle of 400AX15MEFC10X16
When a potential difference is applied across a 400AX15MEFC10X16, a very thin layer of positively-charged ions accumulate at the surface of the electrolyte and a dielectric layer is formed. This layer has a great electrical insulation effect, and the electric charges on the surface of the electrolyte are retained for a long period of time, even when the potential difference is removed. The stored charges create a stored electric field, or capacitance, between the electrodes. Higher values of capacitance are achieved by increasing the thickness of the dielectric layer using an electrolyte like ethanol or manganese dioxide.

The 400AX15MEFC10X16 has a non-polar design, which means it has two connection leads and it can operate regardless of the polarity of the applied voltage. This makes it ideal for AC applications, as it can be used without worrying about reversing the polarity of the voltage.

Aluminum electrolytic capacitors like the 400AX15MEFC10X16 are the most widely used of the electrolytic capacitors and are favoured for AC applications due to their high efficiency, low cost, and high reliability. But due to their reactive nature, these capacitors can only store electric charge for a short period, and they must be replaced periodically.
