Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are electrical components used in a wide variety of electronic devices that are used for storing energy and voltage regulation. They comprise a cylindrical metal shell that contains two electrodes – a cathode (negative terminal) with a paper, foil, or mica dielectric, and an anode (positive terminal) with an electrolyte-soaked aluminum foil. These types of capacitors are commonly used in consumer electronics, automotive circuitry, and power supplies.

LNU2H182MSEGBB Application Field and Working Principle

The LNU2H182MSEGBB aluminum electrolytic capacitor is a radial-leaded, small-sized, polarised, and surface-mounted type of capacitor. It has a capacitance of 18μF, has a diameter of 5.40mm, a height of 10.0mm, and an operating temperature range of -55°C to +105°C. It is ideal for use in automotive, industrial, and consumer applications that require a reliable power source.

The working principle of an aluminum electrolytic capacitor is simple. It contains two electrodes – a cathode and an anode – separated by an electrolyte. When an electrical charge is applied to the two electrodes, the anode becomes charged, and the cathode becomes discharged. The electrolyte allows the current to pass between the two electrodes, creating an electrochemical reaction, which separates ions and stores an inexhaustible amount of electrical energy.

When an AC current flows, the anode charges the capacitor and the cathode discharges it. This creates a capacitive reactance, which helps in regulating the voltage across the capacitor. The capacitor’s size and type will determine its working voltage and capacitance value. The LNU2H182MSEGBB capacitor has a working voltage of 63V DC and a capacitance of 18μF.

When an AC current flows, the capacitor functions as an AC filter, blocking higher frequencies while allowing lower frequencies to pass through. This helps in keeping the current stable, preventing voltage fluctuations, and providing reliable power for the electronic device. In addition, the aluminum electrolytic capacitor helps in protecting the electronic components from corrosion damage and overloads.

The LNU2H182MSEGBB aluminum electrolytic capacitor is ideal for use in a wide range of applications. It is suitable for use in automotive electronics, industrial automation, and consumer electronics. In the automotive industry, it can be used in ECUs, radio systems, wiper and window motors, engine RPM sensors, and battery management.
