ESMH451VQT681MB50T

Aluminum electrolytic capacitors (aka aluminium electrolytic capacitors or AL-E-caps) are polarized capacitors whose anode electrode is made of a pure aluminum foil with an etched surface. The electrolyte, which covers the etched foil, serves as the second electrode of the capacitor. Capacitance values range from 1µF (10-6 F) to 2,200µF (10-6 F) with a working voltage range from 4V DC to 275V DC. Applications for aluminum electrolytic capacitors include surge protection, power supplies, over-voltage protection, DC-DC conversion, single-ended power supplies, as well as high-end audio.

The ESMH451VQT681MB50T is a surface mounted aluminum electrolytic capacitor with non-solid electrolyte, occupying a very limited area of the printed circuit board. It has a capacitance of 0.47µF (10-6F) with a rated voltage of 50V and a maximum operating temperature of 85°C. It has a self-healing property and is resistant to temperature and moisture for reliable performance.

The working principle of the ESMH451VQT681MB50T aluminum electrolytic capacitor is based on the Faraday’s Law of electrolysis. When a voltage is applied between the positive aluminum plate, referred to as the anode, and the electrolyte (or negatively charged electrode) an electric current is established. This electric current produces an electrochemical reaction that results in a thin layer of oxide growing on the anode surface, forming a capacitance. As the voltage increases, the oxide layer grows thicker, resulting in higher capacitance.

In order to maintain the capacitance of the device, it is important to control the temperature and voltage of the device. Temperature plays an important role in the life expectancy of an aluminum electrolytic capacitor; as temperature increases, the life of the capacitor is reduced. In addition, excessive voltages can also damage the device, resulting in an effect known as dielectric absorption which reduces the capacitance and can lead to eventual device failure.

The ESMH451VQT681MB50T aluminum electrolytic capacitor is designed to be used in many different applications. Its small size and low profile make it ideal for use in low-profile electronic devices such as mobile phones and tablet computers. It can also be used for over-voltage and surge protection in power supply systems. It is also used in precision electronic equipment such as medical instruments and military applications for high voltage filtering and protection.

Aluminum electrolytic capacitors are an incredibly important component in many electronic systems. They are ideal for providing power storage and filtering in a wide range of applications. The ESMH451VQT681MB50T aluminum electrolytic capacitor is a small, low profile device that can be used in many different applications in order to provide reliable power storage and filtering.
