Aluminum electrolytic capacitors, sometimes called electrolytic capacitors, are passive electronic components used in a variety of applications. They are widely used in audio, video, telecommunications and computer applications. The MALREKB05DC315J00K is an important category of aluminum electrolytic capacitors.

The MALREKB05DC315J00K is a polarized capacitor, and a type of electrolytic capacitor, meaning it uses an anode composed of aluminum foil with a layer of oxide formed on its surface. The oxide provides a high and reliable dielectric barrier for storing energy. The capacitor also consists of a second electrode (the cathode) formed of a metal roll, which is rolled around the aluminum foil. The metal roll is constructed of a highly conductive material, such as a alloy of manganese and zinc.

The MALREKB05DC315J00K capacitor has a capacitance range of 1nF – 4.7uF. It is a screw-in type capacitor, with a rated voltage of 5 to 16V DC. It has a radial lead type with a overvoltage category rating of C. It also has a rated temperature of 85°C, a capacitance tolerance of ±20%, and a rated dissipation factor of 1.125. Additionally, the MALREKB05DC315J00K has an insulation resistance of at least 3000M at 25°C.

The MALREKB05DC315J00K capacitor is used in a wide range of applications, such as power sources, audio and video equipment, communication, and computer systems. Due to its wide capacitance range, it can be used for various types of power and signal filtering, voltage regulation, and decoupling. Additionally, it is often used in LED driver circuits, lighting, and other electronic devices.

The MALREKB05DC315J00K capacitor’s working principle is based on the electrochemical reaction between aluminum and an electrolytic medium, which leads to the formation of a very thin but highly stable aluminum oxide film on the surface of the aluminum foil. This oxide layer serves as the capacitor\'s dielectric material. The oxide-film is electrically insulated from the aluminum along its entire surface, enabling the capacitor to store the electrical energy without any leakage. The oxidized aluminum acts as the anode, while the metal roll acts as the cathode. This combination creates a polarized capacitor, meaning one of the electrodes (in this case, the anode) must be connected to the positive polarity in order for the capacitor to work.

In summary, the MALREKB05DC315J00K capacitor is a polarized aluminum-electrolytic capacitor with a capacitance range of 1nF to 4.7uF. It is mainly used for filtering, voltage regulation, and decoupling, as well as lighting and LED driver circuits. Its working principle is based on an electrochemical reaction between aluminum and an electrolytic medium, leading to the formation of a very thin but highly stable aluminum oxide film on the surface of the aluminum foil that serves as the dielectric material. The oxide-film is electrically insulated from the aluminum along its entire surface, enabling the capacitor to store energy without any leakage.
