Aluminum electrolytic capacitors are polarized electrolytic capacitors in which the anode is an aluminum foil with a layer of aluminum oxide as the dielectric. The capacitor body is the cathode. Due to the tremendous capacitance values that can be obtained in relatively small and inexpensive units, aluminum electrolytic capacitors are widely used in a variety of applications. The specific 420MXH470MEFCSN25X55 application field and working principle of aluminum electrolytic capacitors are discussed below.

420MXH470MEFCSN25X55 Application Field

This type of capacitor is capable of performing well in circuits where voltage and current fluctuate rapidly. They are mainly used in circuits with high frequency operation, intermediate frequency circuits, and RF blocking filters. These capacitors are also often used for smoothing and maintains peak currents as well as providing filters for high frequency noise signals.

The 420MXH470MEFCSN25X55 series aluminum electrolytic capacitors are mainly applied in the fields of home appliances, automotive electronics, industrial control, communications devices, etc.

420MXH470MEFCSN25X55 Working Principle

The working principle of aluminum electrolytic capacitors is based on the structure of the capacitor. The anode is an aluminum foil with a layer of aluminum oxide as the dielectric. The cathode is formed by the capacitor body, and electrolyte is impregnated in the capacitor. The thickness of the oxide layer determines the capacitance, the higher the capacitance, the thicker the oxide layer. As the voltage across the capacitor increases, electric current flow through the capacitor increases, and a correspondingly larger electrostatic charge is stored on the dielectric oxide layer.

When an AC current is applied to the circuit, the capacitor functions as a current limiter because the reactance of the capacitor changes with the frequency of the applied current. During each cycle of the AC current, the capacitor charges and discharges alternately, and the charge and discharge current have different values. This allows a capacitor to reduce the current and voltage of AC signals, which can be used to filter out high frequency audio signals or reduce the amount of power lost in power conversion applications.

The 420MXH470MEFCSN25X55 series aluminum electrolytic capacitors are exceedingly reliable and have a long working life thanks to their design and durable construction. The capacitors have a highly efficient temperature range that ensures long-term, reliable operation.
