Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are widely used in a variety of consumer, industrial, and automotive applications because of their large capacitance in a small volume and low cost. The most frequently used type of aluminum electrolytic capacitor is the non-solid style. The common characteristics of non-solid capacitors includes a low equivalent series resistance (ESR) and low ripple current capabilities. This makes them highly suitable for energy storage and power supply applications.

The particular type of aluminum electrolytic capacitor that will be discussed here is the LQR2W103MSEJBB, which is a surface mount non-solid capacitor with an operational temperature range of -40 to +105°C. It also has a rated ripple current of 800mA and a rated voltage rating of 35 VDC.

The LQR2W103MSEJBB has two components; a cylindrical aluminum can with a sealed end and a sealing member which is usually made of epoxy resin or nylon. The can itself contains a preform and holds the electrolyte, typically a mixture of aluminum oxide, boric acid, water, and ethylene glycol. It also has two electrodes, an anode and a cathode, located on opposite ends of the can. When a voltage is applied to the electrodes, the salt bridge between the two creates an electric field which causes the aluminum oxide to form a thin film on the anode. This thin film is what stores charge and provides the capacitor with its capacity.

The capacitance of the LQR2W103MSEJBB is 105µF, with a tolerance of ±20%. This means the actual capacitance of the component can vary from as little as 84µF to as much as 126µF (105 ±20%). The LQR2W103MSEJBB also has a self-healing feature that prevents it from shorting out at higher operating temperatures. This feature helps increase its life expectancy and ensures optimal performance. It also has an Equivalent Series Resistance (ESR) of 0.027Ω.

The LQR2W103MSEJBB is designed for a wide range of consumer, industrial, and automotive applications. In consumer applications, such as electronic inverters, televisions, and computers, they are used to help control energy demand and reduce overall power consumption. In industrial applications, these capacitors are used to store and provide high-frequency ripple currents for power supplies and motor drives. In automotive applications, these capacitors are used to reduce the amount of noise emitted from the vehicle\'s electrical system.

Because of their low ESR and high ripple current ratings, the LQR2W103MSEJBB is an excellent choice for applications that require a long operational life. Its ability to store large amounts of charge in a small volume makes it an ideal choice for energy storage and power supply applications.

Overall, the LQR2W103MSEJBB is an excellent choice for many consumer, industrial, and automotive applications. Its low ESR, high ripple current ratings, and long operational life make it an ideal choice for energy storage and power supply as well as noise reduction. Its ability to store large amounts of charge in a small volume makes it an excellent choice for circuit designers who need reliable, cost-effective components for their designs.
