Aluminum electrolytic capacitors are widely used components in electronic circuits. This article will discuss the advantages and disadvantages of the MAL203638689E3, an aluminum electrolytic capacitor, as well its application field and working principle.

Advantages

The MAL203638689E3 has many benefits over other aluminum electrolytic capacitors. For starters, its maximum operating temperature is a high 125℃, which is higher than most other aluminum electrolytic capacitors on the market. In addition, this aluminum electrolytic capacitor has a voltage rating of 35 V, and can handle up to 100 kHz ripple current.

The MAL203638689E3 also features a low equivalent series resistance (ESR), and high capacitance values (up to 39μF). Moreover, its lead pins come in a variety of finishes, including gold, nickel and tin. This makes it compatible with a wide variety of electronic components.

Furthermore, the MAL203638689E3 contains a liquid electrolyte and an electrolytic foil, which gives it the capability of storing more energy than other types of capacitors. This makes it an ideal choice for applications that require high energy storage, such as switching power supplies and energy conversion circuits.

Disadvantages

The MAL203638689E3 also has some drawbacks. This aluminum electrolytic capacitor’s relatively high ESR values can cause it to overheat and may reduce its lifetime. Additionally, its large physical size may make it difficult to use in applications where space is limited, such as portable devices.

Furthermore, this aluminum electrolytic capacitor requires a specific polarity when connecting its lead pins. If the polarity is reversed, it will cause the capacitor to fail. This is because the current in the electrolytic foil first builds up, then slowly decreases.

Application Field

The MAL203638689E3 can be used in a wide range of applications. For instance, it can be used for signal filtering in communication circuits, energy storage for switching power supplies, and voltage regulation in audio amplifiers. Additionally, this aluminum electrolytic capacitor can be used in DC-DC converters, and for snubber circuits in insulated gate bipolar transistors (IGBTs).

Working Principle

The MAL203638689E3 utilizes an electrolytic foi, a porous material that separates the cathode and anode legs. When an electric current passes through the electrolytic foil, an oxide film is created on the surface of the electrodes. This oxide film acts as a dielectric, allowing the capacitor to store energy.

When a voltage is applied to the capacitor, the film is polarized and a small space charge forms between the electrodes. This space charge creates an electrostatic field, allowing the capacitor to store energy in the form of a static electric charge.

When the capacitor is discharged, the field is reversed and the stored energy is released in the form of an electric current. This is why the MAL203638689E3 aluminum electrolytic capacitor is ideal for applications that require large amounts of energy storage.

In conclusion, the MAL203638689E3 is a high-quality aluminum electrolytic capacitor with many advantages over other capacitors. It has a high operating temperature, low ESR, long lifetime, and high capacitance values. It also comes with lead pins in a variety of finishes. Furthermore, it can store large amounts of energy and can be used for signal filtering, energy storage, voltage regulation, and DC-DC converters.
