Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a type of capacitor that uses an aluminum foil with an oxide layer as the anode and other form of metal as the cathode. They are commonly used due to their high energy density and low cost. The LAQ2D391MELZ35 series is a high-voltage aluminum electrolytic capacitor which offers a wide selection of case sizes and capacitance values.

Application Fields

An LAQ2D391MELZ35 capacitor’s application fields can be divided into four areas. The first is in the power supply field. These capacitors are capable of efficiently supplying power to circuits whether it’s in AC or DC form. This makes them a good choice for power supplies and other power applications.

Another application field is in low frequency and high frequency circuit designs. These capacitors are suitable for low frequency circuits and high frequency switching circuits due to their high ripple current characteristics, making them a reliable choice for these circuit designs.

The third application field is in audio equipment. The use of these capacitors in audio equipment is important to create high-quality sound. They are used in the crossover networks, amplifiers and other pieces of audio equipment to produce high quality sound.

Finally, these capacitors can be used in safety circuits to protect electronic devices from spikes in voltage. They are used in these features due to their high voltage capability and their reliability for providing protection.

Working Principles

The LAQ2D391MELZ35 aluminum electrolytic capacitor works by storing energy on the positive anode foil. The positive anode foil is usually made of aluminum and has an oxide coating. This oxide coating provides a barrier between the anode and the electrolyte inside, allowing it to store energy as charge

The negative cathode foil is usually made of metal such as tin or zinc and is also coated with an oxide layer to prevent current leakage. The combination of the two foils forms the capacitor with an air or gas gap in between them.

The capacitor is then filled with an electrolyte liquid or solid. This liquid or solid contains ions that are able to move between the cathode and anode foils. This movement of the ions allows charge to be accumulated between the two foils and stored as energy.

When a voltage is applied across the capacitor foils, charge is transferred from the anode to the cathode. If the current flow is sustained, the capacitor will reach its maximum charge, at which point it will act as a short circuit.

The LAQ2D391MELZ35 is capable of withstanding a large amount of charge, up to 400VDC, allowing the capacitors to be used in a wide variety of applications.
