Aluminum Electrolytic Capacitors, such as the MAL201356228E3, have a wide variety of applications and working principles. As the name suggests, these capacitors are made from aluminum and consist of an anode, a dielectric layer, and a cathode or electrolyte.

The main applications of aluminum electrolytic capacitors are for the reduction of noise, filtering of frequencies, energy storage, and power supply smoothing. In terms of noise reduction, capacitors can be used to filter out higher frequency noise, which is especially helpful in audio applications. This is achieved by charging the capacitor with current corresponding to the frequency of the noise. The higher frequencies cause the capacitor to discharge quicker, effectively dampening and reducing the noise.

When used to filter frequencies, capacitors can be used to separate two signals while allowing only those within designated frequencies to pass through. This is done by passing both signals through the capacitor, which then selectively allows only the target frequencies to pass. This is commonly seen in audio applications as well.

Capacitors are also used in power supply smoothing because of their capacity to store energy. A capacitor can store energy when the supply voltage is higher than the voltage on the capacitor, and can discharge when the voltage on the supply is lower than the voltage on the capacitor. This allows for the fluctuations in voltage to be smoothed out.

Aluminum electrolytic capacitors can also be used as energy storage devices. When a capacitor is charged, it can store the energy and release it when needed. This is especially useful in applications such as electrical regulation or to provide consistent energy output over a certain period of time.

The MAL201356228E3 aluminum electrolytic capacitor is specifically designed for use in DC, DC/DC converters, and similar applications. It has a wide operating temperature range from -55°C to +105°C and is designed to limit the voltage ripple and absorb transitor generated noise. It’s also designed to handle surges up to 20A.

The working principle of the MAL201356228E3 is based on the same principles as other aluminum electrolytic capacitors. It contains two metal plates, an anode and a cathode, separated by an insulating layer. Within the capacitor, a thin oxide layer forms on the anode when connected to a voltage source.

The oxide layer can only pass a limited amount of current, which creates a barrier between the two metal plates. This limits the electric current in microseconds and allows for higher capacitance, as charged particles are “trapped” in the thin oxide layer. When voltage is applied, the molecules will be more efficiently rearranged, further increasing the capacitance.

The size of the MAL201356228E3 is 10mm x 22.5mm with a voltage rating of 35V and capacitance of 2200μF. It has an endurance of 2000hours at 85°C and can withstand a maximum ripple current of 1.5A.

In conclusion, aluminum electrolytic capacitors, such as the MAL201356228E3, have a wide range of applications and a basic working principle. They are used for noise reduction, filtering frequencies, energy storage, and power supply smoothing, and can handle surges up to 20A. The MAL201356228E3 has a voltage rating of 35V and capacitance of 2200μF and can handle a maximum ripple current of 1.5A.
