Aluminum Electrolytic Capacitors–EKMQ250ELL102MJ16S Application Field and Working Principle

Aluminum electrolytic capacitors are a kind of polarized capacitors. They are composed of an aluminum anode foil, an electrolyte, a separator and an aluminum cathode foil. Their purpose is to store and release electrical energy. Aluminum electrolytic capacitors are widely used in many electronics, such as various consumer electronics, TV, radio receivers, and power supplies. In this article, we will introduce the application field and working principle of the aluminum electrolytic capacitor—EKMQ250ELL102MJ16S.

Application Field

The EKMQ250ELL102MJ16S aluminum electrolytic capacitor has a range of application fields. It can be used for amplifiers, various types of audio equipment, various types of power supplies, computers, industrial machinery, and automotive electronics. It can also be used for audio frequency filter circuits, IC power supply filters, high frequency bypass circuits, oscillators, as well as electronic toys, and electronic clocks.

Working Principle

The working principle of the EKMQ250ELL102MJ16S aluminum electrolytic capacitor is quite simple. The two poles are connected to an electrical signal. As current moves from one pole to the other, a charge accumulates in each aluminum anode. Due to the effect of the electrolyte, a layer of oxide film forms on the surface of the anode, forming an insulating layer between the two poles. This causes the capacitance to increase, allowing the capacitor to store the electrical signal.

When the electrical signal changes direction, the layer of oxide film begins to break down, allowing current to flow easily and release the stored energy. After the capacitor has released the energy, it takes some time for the oxide film to re-form and the capacitance to increase again. Thus, the aluminum electrolytic capacitor can store and release electrical energy.

Conclusion

The EKMQ250ELL102MJ16S aluminum electrolytic capacitor is a type of polarized capacitor composed of an aluminum anode, an electrolyte, a separator, and an aluminum cathode. It has a wide range of application fields and is used for various purposes, such as audio frequency filter circuits, IC power supply filters, high frequency bypass circuits, oscillators, electronic toys, and electronic clocks. Its working principle is based on the accumulation and release of electrical charge on an oxide film layer between the two poles.
