Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are essential components in many electronic devices. They are widely used for filtering and blocking, and for other applications such as timing, power supply decoupling and ripple current reduction. In this article, we will focus on EMVK250ADA331MJA0G, a type of aluminum electrolytic capacitor, and its application field and working principle.

Description

EMVK250ADA331MJA0G is a cylindrical aluminum electrolytic capacitor with Japanese origin. Made of aluminum electrolytic material, this capacitor features a rated voltage of 250V, capacitance value of 3300μF, high frequency characteristics, and an EIA size of 22 x 45mm. The product is available in D case and utilizes non-solid electrolyte, which provides greater stability when subjected to large temperature and humidity changes.

Application Fields

One of the main applications of EMVK250ADA331MJA0G is for power supply decoupling in various electronic devices. As power supply voltage fluctuates, this capacitor is used to reduce ripple current and to create clean voltage. It can also employed in high frequency filters and with discerning heavy duty motors.

This capacitor is also used in a wide range of electronic products such as industrial robots, clocks, timers, switching power supplies, lighting systems, toys, satellite systems, power amplifiers and automotive electronics. It is also widely used in aerospace industry and medical equipment.

Working Principle

EMVK250ADA331MJA0G is an electrolytic capacitor that takes advantage of the principle of dielectric polarization. The process of dielectric polarization is when positive and negative charges of equal magnitude create a charge separation. This charge separation leads to the formation of an electric field in the surrounding material, which acts as a dielectric field.

The capacitor consists of two metal plates that are separated by the dielectric field. The plate on one side of the capacitor is connected to the negative terminal, while the plate on the other side is connected to the positive terminal. When a voltage is applied to the capacitor, the electric field of the dielectric material is aligned in the direction of the applied voltage. This results in a capacitance value, which is a measure of the energy stored in the capacitor.

The capacitance value of EMVK250ADA331MJA0G is 3300μF. The amount of energy stored in the capacitor is dependent on the applied voltage, temperature, and the type of dielectric material used. The capacitor also has a self-healing property, which means that it can withstand transient surges and return to its normal capacitance value after the surge.

Conclusion

EMVK250ADA331MJA0G is a type of aluminum electrolytic capacitor with a rated voltage of 250V and a capacitance value of 3300μF. This type of capacitor is used in a wide range of electronic devices for power supply decoupling and filtering. It utilizes the principle of dielectric polarization to create an electric field, which is responsible for the capacitor’s energy storage. Thanks to its self-healing property, it is able to withstand transient surges and return to its normal capacitance value after the surge.
