EKMH250VNN123MQ40S

Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are one of the most commonly used capacitors due to their low cost and relatively large capacitance. They are made with a thin aluminum oxide layer sandwiched between two aluminum electrodes. The oxide layer acts as the dielectric and allows the capacitor to hold a large amount of charge, making it an ideal choice for a wide variety of applications.

The EKMH250VNN123MQ40S is an aluminum electrolytic capacitor. It is a Radial Lead type, with a rated voltage of 250V and a maximum ripple current of 40A.

Application Field

The EKMH250VNN123MQ40S is a general purpose capacitor and is suitable for power electronic applications such as PFC circuits, SVR circuits and other high-current/high-frequency circuits. It is also suitable for use in automotive, telecom and consumer electronics applications such as DC-DC converters, power supplies and flash lighting.

Working Principle

When current flows through the capacitor, it produces a magnetic field between the aluminum electrodes that causes the oxide layer to become charged. This charge allows the capacitor to store energy and use it later when needed. As the energy is discharged, the capacitor will slowly start to lose its charge. When the voltage across the capacitor falls below a certain level, it will need to be recharged, usually with an external power source.

The amount of energy that can be stored in an aluminum electrolytic capacitor depends on its size and capacitance. Generally, larger capacitors can store more energy than smaller ones, but this comes at a cost: larger capacitors are more expensive and require more space.

Conclusion

The EKMH250VNN123MQ40S aluminum electrolytic capacitor is a widely used component in a variety of power electronic, automotive, telecom and consumer electronic applications. Its large capacitance and relatively low cost make it an ideal choice for most applications.
