Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, also known as electrolytic capacitors, are one of the most commonly used capacitors. The structure is a capacitor formed by combining a thin oxide layer formed on the surface of an aluminum foil as the anode of the capacitor, a separator soaked in liquid electrolyte (or solid electrolyte) as the dielectric layer, and a metal as the cathode of the capacitor. . Electrolytic capacitors are divided into two types: liquid electrolyte and solid electrolyte.

LKX2G151MESY45 Application Field and Working Principle

The LKX2G151MESY45 is a common aluminum electrolytic capacitor, which mainly has the following three application fields:

1. DC filter circuit: Aluminum electrolytic capacitors are widely used in DC filter circuits. The DC filter circuit can reduce the ripple of the power supply, and at the same time can suppress high frequency interference.

2. Clock circuit: Aluminum electrolytic capacitors can also be used as a timing element for timing functions in some clock circuit applications. The clock circuit formed by the LKX2G151MESY45 can precisely unlock system activities, and control system time with high precision.

3. Timing circuit: The LKX2G151MESY45 not only plays an important role in the clock circuit, but also plays an important role in the timing circuit. When the timing circuit is formed, the capacitance of the aluminum electrolytic capacitor continuously charges and discharges, and then drives the driving circuit to control the timing of the switch on and off of the electrical system.

The working principle of the LKX2G151MESY45 aluminum electrolytic capacitor can be explained by the following charging and discharging circuits. When the voltage across the capacitor is changed, the current will be generated, causing the electric charge to flow into and out of the capacitor, resulting in the change of the voltage across the capacitor. The voltage and current of the capacitor vary as each charging and discharging cycle.

When the LKX2G151MESY45 starts to charge, the charging current changes the capacitor to a higher potential, the voltage rises, and the capacitor has a charging current. When the LKX2G151MESY45 is discharged, the capacitor releases its charge until the capacitor reaches the zero potential state. Then the capacitor has a discharging current and the voltage drops. The voltage and current of the capacitor vary as each charging and discharging cycle.

The current flowing through the LKX2G151MESY45 aluminum electrolytic capacitor during the charging and discharging process is called the charging current and the discharging current respectively. This charging and discharging current changes the charge on the capacitor, resulting in a change in the potential of the capacitor.

In conclusion, the LKX2G151MESY45 aluminum electrolytic capacitor is mainly used in DC filter circuit, clock circuit, and timing circuit, and works based on the charging and discharging principles.
