Aluminum Electrolytic Capacitors are a vital component in electronics, offering high capacitance at relatively low cost. One such capacitor, the MAL211938229E3, is a radial-lead type aluminum electrolytic capacitor manufactured by Palotron Technologies. It offers high capacitance, robust construction, and a long life span. This article will discuss the application field and working principle of the MAL211938229E3.

Application Field of the MAL211938229E3

The MAL211938229E3 is used in a wide variety of electronic devices, such as sound systems, computers, regulators, switches, and telecom equipment. It can also be used in other devices such as radio frequency (RF) modules and automotive power modules. Additionally, it can be used as a voltage-doubling capacitor and can be advantageous in boost or buck regulators, as well as pulse width modulation (PWM) converters. Its compact size and low profile make it suitable for use in various audio and video applications.

Working Principle of the MAL211938229E3

The MAL211938229E3 inherits the conventional working principle of aluminum electrolytic capacitors, which are constructed with two metalized electrodes, an electrolyte, and a separator. One electrode is the anode and is composed of pure aluminum foil, which acts as a dielectric. The other electrode is the cathode and is composed of a mixture of aluminum foil and activated charcoal, which acts as a surface adsorbent. A separator is sandwiched between the two electrodes, and the electrolyte, typically an acidic aqueous solution, fills the pores of the separator. A sleeve and rivet then act as the external conductor, and an insulator between the sleeve and terminal block gives additional dielectric protection.

When AC current is applied to the MAL211938229E3, a capacitance forms between the two electrodes. Since aluminum possesses an exceptional ability to adopt a higher dielectric constant at higher frequencies, the capacitor is valued highly in audio and video applications involving frequencies in the audible range.

Because the capacitor employs a wet electrolyte, it can leak over time, corroding the anode and causing it to lose its dielectric constant, thereby diminishing its capacitance. In order to increase capacitance, the amount of aluminum on the anode must be renewed often. This process is known as “reforming”, and aluminum electrolytic capacitors such as the MAL211938229E3 must be reformed after a certain period of time.

Conclusion

The MAL211938229E3 is a radial-lead type aluminum electrolytic capacitor manufactured by Palotron Technologies. It offers high capacitance, robust construction, and a long life span, and can be used in a wide variety of electronic devices. Its compact size and low profile make it suitable for use in various audio and video applications. It employs the conventional working principle of aluminum electrolytic capacitors, and must be reformed after a certain period of time in order to increase capacitance.
