Aluminum electrolytic capacitors (AECs) are capacitors which store charge between two electrodes which are separated by an electrolytic medium. AECs are notable for their small size, high energy density, and low cost, which makes them ideal for use in a variety of applications. The EKMM251VNN102MR50T is a type of AEC that is widely used. In this article, we will discuss the application fields and working principle of the EKMM251VNN102MR50T.

Application Fields

The EKMM251VNN102MR50T is a low profile, high capacitance AEC. Due to its small size and high capacitance, it is commonly used in applications where space is at a premium such as in space-constrained consumer electronics, laptops and mobile devices. It is also used in automotive applications such as engine control modules, air bags and power steering. Other application areas include consumer electronics, telecommunications, automotive, consumer appliances and medical equipment.

Working Principle

The EKMM251VNN102MR50T is an Aluminum Electrolytic Capacitor which consists of two electrodes separated by an electrolytic medium. The two electrodes are typically aluminum foils with a special etch surface. The electrolytic medium is typically a combination of a solid electrolyte and an absorbent paper sheet .When a voltage is applied across the electrodes, an electric field is created between them. This electric field causes the electrolyte molecules to electrostatically attract each other, allowing them to accumulate on the electrodes. As they accumulate, the gap between the electrodes is reduced, creating a barrier which stores electrical energy.

When the voltage is removed, the electrolyte molecules will be released from the electrodes and flow back towards the electrolyte. This process forms an electrical circuit which will vibrate as the capacitance charges and discharges, creating an oscillating current.

AECs are often used in filtering and power-conversion applications due to their low ESR and high capacitance. In these applications, the oscillating current created by the AEC can help reduce ripple and improve power quality. Additionally, due to their low cost and small size, AECs are used to increase the capacitance of power supplies, allowing them to supply higher currents and wider voltage ranges.

Conclusion

The EKMM251VNN102MR50T is an Aluminum Electrolytic Capacitor which is widely used due to its small size, high capacitance and low cost. It is commonly used in space-constrained consumer electronics, laptops, mobile devices, automotive applications, consumer electronics, telecommunications, consumer appliances and medical equipment. The capacitor works by creating an electric field between two electrodes which causes the electrolyte molecules to electrostatically attract each other, allowing them to accumulate on the electrodes. This creates a barrier which stores electrical energy, allowing the capacitor to be used in filtering and power-conversion applications.
