Aluminum electrolytic capacitors are widely used in the electronics industry because of their advantages of high capacitance in a small size, low ESR values, and surpassing other forms in terms of energy storage capacity. The MAL211990503E3 model aluminum electrolytic capacitor belongs to a type of SP-CAP, which is a kind of snap-in type that helps reduce mounting space in applications. This series is particularly suitable for use in AC adapter, LCD monitor, TV sets, and STB boxes.

The design of the MAL211990503E3 is based on the traditional SP-CAP structure of aluminum electrolytic capacitors. It has an aluminum can with a screw connection and a plastic case. The can is divided into two parts, with an inner part and an outer part. The inner part has electrodes and aluminum electrolyte both in the inner and outer parts. The outer part has an outer jacket and the case is filled with a sealing wax and aluminum electrolyte. The outer jacket serves to protect the inner components. The edges of the electrodes in the inner part are sealed to the inner wall of the outer part, forming a complete structure to hold the components in place.

In operation, the high-frequency alternating current enters the capacitor through the inner part, which stores the electric energy. The insulated internal resistance of the capacitor allows electrons to flow through the electrolyte and the aluminum can, while the charge is accumulated on the capacitor\'s electrode. As the current through the capacitor reaches its maximum level, the stored charge starts to dissipate and provide power to the connected circuit. As the process repeats, the capacitor is able to discharge and store energy repeatedly.

The MAL211990503E3 is mainly designed for application in power supplies, inverters, and AC adapters, and is highly reliable in terms of its capacitance, reliability, and energy efficiency. Its compact design makes it suitable for use in smaller spaces, and the snap-in structure enables easy installation and replacement. This series offers an insulation resistance of 5000 MΩ, with an operating temperature range of -40°C to +105°C, and a long life-span of 5,000 hours.

In addition, the MAL211990503E3 series features a durable and strong plastic case, and a superior dynamic characteristic that ensures optimal performance on high frequency circuits. Its excellent energy-storage capacity makes it ideal for high frequency circuits, and the low impedance makes it capable of handling high energy loads. Its low ESR value also provides exceptionally good ripple current tolerance.

In conclusion, the MAL211990503E3 is a popular aluminum electrolytic capacitor that is designed to meet the needs of various applications in power supplies, inverters, and AC adapters. It is reliable and efficient in terms of performance and energy storage, and its snap-in structure allows for easy installation and replacement. Overall, this model is a great choice for any electronic system that requires high capacitance.
