Aluminum Electrolytic Capacitors

MAL214858102E3 application field and working principle

Aluminum electrolytic capacitors or Polarized capacitors are one of the most widely used types of capacitors in electronics. The mal214858102E3 (hereafter referred to as the “152E3”) is a typical example of an electrolytic capacitor. It features a long life, high capacitance, and low equivalent series resistance (ESR), making it suitable for use in a wide variety of in a variety of electronic applications.

Application field

The 152E3 is used mostly in consumer and industrial electronic applications, such as surge protection, high frequency and power circuit filters, and sound suppressing circuits. It is also used in automotive electronics, solar energy systems, and a variety of other electronic products.

Due to its long life, high capacitance, and low ESR, the 152E3 can be used as a replacement for other types of aluminum electrolytic capacitors or even ceramic capacitors in power filtering applications. It can also be used in low frequency filtering applications, such as power supplies, as a cost-effective solution.

Working principle

The 152E3 is an aluminum electrolytic capacitor. As such, it consists of two aluminum foil anodes, one of which is etched to form a porous layer, which is impregnated with an electrolytic solution. The anode is then placed inside of a paper or plastic dielectric material and rolled into a cylindrical shape. The other anode is then placed outside of the dielectric material and a cylindrical casing is placed around them. This cylindrical casing also serves as the external terminals of the capacitor.

In operation, when the capacitor is connected to a voltage source, current flows from the terminal connected to the positive terminal of the voltage source to the anode through the electrolytic solution, thus charging the capacitor. The anode is then held at a higher potential than the other terminal, allowing a current to flow through the capacitor when a potential difference is applied across its terminals. This current flowing through the capacitor is called the charging current.

When a power supply is applied to the capacitor, the charging current flows through the various parts of the capacitor, resulting in an accumulation of electric charge on the anode. This electric charge is stored within the capacitor and can be discharged rapidly when required.

Conclusion

The 152E3 is an aluminum electrolytic capacitor and is used mainly in consumer and industrial electronics applications. It features a long life, high capacitance, and low ESR, making it suitable for a variety of applications. It is also used for power filtering applications and as a replacement for other aluminum electrolytic capacitors or even ceramic capacitors. Its working principle is based on the capacitor storing electric charge on its anode when connected to a voltage source.
