Aluminum Electrolytic Capacitors (AECs) are a type of capacitor that utilizes a static electric charge to store and release electrical energy. The most common type is a polarized aluminum electrolytic capacitor, which consists of two metal plates with an electrolytic solution in between. The two plates are made from aluminum foil and have a thin oxide layer called a dielectric. The electrolyte used in AECs can be liquid (water-based) or solid (acrylic-based) and determines the capacitance, voltage rating, and height of the capacitor. The term "LQR2W103MSEJBN" refers to a specific type of aluminum electrolytic capacitor, which has a capacitance of 100µF, a voltage rating of 25V, and a height of 7.3mm. Its application consists of providing power or ground for low-power, high-speed electronic devices, such as mobile phones, tablet PCs, and digital cameras.

As with all capacitor types, the working principle of LQR2W103MSEJBN is based on the concept of capacitance, which is the ability of a device to store electrical charge. When a voltage is applied across its two metal plates, it creates an electric field and causes an exchange of charge between the plates. This exchange of charge creates an electric field of its own and is called an electric double layer. This double layer stores the charge and, when the voltage source is removed, it dissipates the charge back into the system. This process is repeated continually as voltage is cycled across the metal plates, thereby allowing the capacitor to store and release energy on demand.

Aside from storing and releasing energy, LQR2W103MSEJBN can be used for filtering as well. In this application, a voltage is applied across the plates, and the capacitor is placed in line with the signal being filtered. This attachment creates a high-pass filter, wherein only signals with frequencies greater than the cut-off frequency can pass through. This type of filter is particularly useful for removing static or background noise from signals, such as audio signals.

LQR2W103MSEJBN capacitors are typically used in consumer electronics, automobiles, and medical devices due to their small size, high capacitance, and low cost. Additionally, they are ideal for applications such as motor control, switching power supplies, power supplies, and rectification. As the circuit boards used in these applications continue to shrink in size, AECs will remain a vital piece of the puzzle and will continue to play a major role in the future of electronic design.
