Introduction

Aluminum electrolytic capacitors, also referred to as “Al-electrolytics”, are non-polarized electrochemical capacitors that provide excellent levels of capacitance, endurance, and stability for electronic circuits. As the name implies, these capacitors consist of an aluminum anode and a cathode that are immersed in an electrolytic solution (typically containing ethylene glycol). The anode and cathode are electrically connected and the electrolyte solution acts as the dielectric material. The MAL210178683E3 is a type of surface- mounted aluminum electrolytic capacitor, which offers a high volume capacitance and a wide range of operating temperature. This article will cover the application field and the working principle of the MAL210178683E3.

Application Field

The MAL210178683E3 is best suited for various application fields due to its excellent characteristics. Among these fields are audio-visual equipment, medical equipment, office automation, domestic appliances, power supplies, lightings, UPS systems, and automotive electronics. Its low profile and low-inductance construction make it well-suited for applications where space is a factor. Its surface-mounting profile also makes it suitable for modern surface-mount applications in which space conservation is a primary necessity. Additionally, the MAL210178683E3 is characterized by its high rated voltage and capacitance and a wide temperature range. Its rated voltage is up to 16V, making it ideal for use with high-voltage power supplies and devices. It is also exceptionally resistant to temperature, heat, humidity, and shock, allowing it to endure in a variety of harsh environments.

Working Principle

The working principle of the MAL210178683E3 capacitor is based on the electrochemical nature of its materials. As discussed previously, the capacitor consists of an aluminum anode and cathode that are immersed in a special electrolyte solution. The electrolyte solution works as a dielectric material. When a voltage is applied to either pole of the capacitor, the two plates are polarized such that the positive charge accumulates on one plate and the negative charge accumulates on the other. This charge accumulation creates an electric field between the plates and increases the capacitance of the capacitor. The size and shape of the capacitor also affects its capacitance or C value. In the case of the MAL210178683E3, the C value can be adjusted by increasing or decreasing the surface area of the plates. A larger capacity value can be obtained by using larger plates or by increasing the distance between the plates. Similarly, a lower capacity value is achieved by decreasing the plate size or reducing the plate distance. The dielectric media between the plates also affects the C value. The MAL210178683E3 capacitor is filled with special electrolyte solution which has a high dielectric constant. This increases the capacitor\'s capacitance or C value.

Conclusion

The MAL210178683E3 is a surface-mounted aluminum electrolytic capacitor that is characterized by its excellent levels of capacitance, endurance, and stability. It is most suitable for applications where space is a factor, and is used in audio-visual equipment, medical equipment, office automation, domestic appliances, power supplies, lightings, UPS systems, and automotive electronics. The working principle of the capacitor is based on its electrochemical nature, in which the anode and cathode create an electric field which increases its capacitance. The plate size and dielectric media of the capacitor can be adjusted to vary its capacitance.
