Aluminum Electrolytic Capacitors and EKXG451ETD4R7MJ16S

Aluminum Electrolytic Capacitors (AECs) are widely used in a variety of electronics applications. They are characterized by their ability to store large amounts of electrical charge, making them suitable for use in high-voltage circuits and power converters. AECs consist of an anode and a cathode, which are separated by an oxide layer. In the positive terminal, an electrolyte is typically poured onto the anode, forming a polarized capacitor.

EKXG451ETD4R7MJ16S is an Aluminum Electrolytic Capacitor from Nippon Chemi-con. The device has low ESR and low leakage current, making it suitable for high frequency applications such as RF power gain stages. It has a rated capacitance of 4.7µF and a rated voltage of 200V. The device is constructed of robust aluminum foil electrodes with a conductive polymer electrolyte. The device also features a universal polarity and is suitable for high ripple current applications.

The primary application field for the EKXG451ETD4R7MJ16S is high frequency switching converters. The device is designed to minimize ESR and leakage current, making it well-suited for the fast switching and large current pulses associated with high frequency power conversion. The device is also suitable for noise suppression applications, and is an ideal choice for decoupling and smoothing applications.

Regarding the working principle of the EKXG451ETD4R7MJ16S, the device acts as a dielectric barrier between the electrodes of the capacitor. When an AC voltage is applied to the capacitor, a current flows through the anode and cathode, while an electrical field is generated by the anode and the cathode sides of the capacitor. This in turn creates an insulating oxide layer between the anode and cathode, thereby preventing further current flow and maintaining the stored electrical charge in the capacitor.

In conclusion, the EKXG451ETD4R7MJ16S is an Aluminum Electrolytic Capacitor designed for high frequency applications. The device has low ESR and low leakage current properties, and is well-suited for the high speed switching and large current pulses required for DC-DC converters, noise suppression, and decoupling/smoothing. The device works by generating an insulating oxide layer between the anode and cathode, which prevents current flow and maintains the stored electrical charge in the capacitor.
