LGJ2E181MELB15 Application Field and Working Principle

An aluminum electrolytic capacitor, also known as an aluminium electrolytic capacitor, is a polarized, non-solid, electrolytic capacitor with a aluminum oxide as the dielectric. It is constructed from two aluminum foils with an electrolytic paper, typically wet deep anodized, as the separator. The electrolyte-soaked paper and foils act as the two electrical plates. In the capacitor, the anode (positive) layer is made by coating one aluminum foil with another silicon oxide and the cathode layer is composed of thin aluminum electrolyte. The aluminum electrolytic capacitor is widely used in different types of electronic circuit, including power supplies, audio amplifiers, sound processing circuits, and medical equipment.

The LGJ2E181MELB15 aluminum electrolytic capacitor is manufactured according to the international standards and produces high performance. Its rated capacitance is 18uF, temperature range is - 40 to + 85°C, maximum ripple current is 191mA, and operating voltage is 16V. The LGJ2E181MELB15 has a durability rating of 2,000 hours at 85°C with zero rated ripple current.

The working principle of the LGJ2E181MELB15 capacitor is based on the principle of electrostatic capacitance. When a voltage is applied to the two plates, it causes a charge separation, resulting in attraction of opposite charges and repulsion of similar charges. This generates an electrostatic field across the dielectric of the capacitor, maintaining an electrical charge. The extremely thin barrier between the two plates, formed by the anodic oxide layer and electrolytic paper, creates an extremely large capacitance value relative to the size of the capacitor, making the LGJ2E181MELB15 capacitor especially useful in high-frequency, high-current electronic circuits.

The LGJ2E181MELB15 aluminum electrolytic capacitor is widely used in many electronic applications, such as power supplies, audio amplifiers, sound processing circuits, and medical equipment. The LGJ2E181MELB15 is well known for its excellent high-frequency, high-current characteristics, which makes it especially suitable for high-frequency, high-current circuits. Furthermore, it has a low equivalent series resistance, which helps to reduce power loss in the circuits. These features make the LGJ2E181MELB15 aluminum electrolytic capacitor a well-known and efficient choice in the industry\'s electronic circuits

In conclusion, the LGJ2E181MELB15 aluminum electrolytic capacitor is a highly efficient device for electronic applications, especially high-frequency, high-current circuits. The capacitance, temperature range, maximum ripple current, and operating voltage of the device all make it desirable for use in variety of electronic applications. The construction of the capacitor, which relies on the principle of electrostatic capacitance, also contributes to ensuring the longevity and efficiency of the device in various applications.
