Aluminum electrolytic capacitors are widely used both in electrical and electronic equipment and have a wide range of applications across a variety of industries. One such capacitor, the EEV-HB0G221P, is no different, offering excellent frequency response, extended life and high power handling capabilities. Where, then, should these capacitors be used and what is their working principle?

Construction of an EEV-HB0G221P

The EEV-HB0G221P is a two terminal anodized aluminum electrolytic capacitor with a rectangular aluminum case. The capacitor consists of an anode, a dielectric, a semiconductor and a cathode, all contained in an electrolytic medium. The anode is a thin aluminum film deposited on the aluminum case and the dielectric is a layer of oxide film on the anode. The semiconductor is contained within a dielectric material and acts as a barrier between the anode and the cathode. The cathode is an aluminum foil which is plated with a thin layer of nickel.

Characteristics of an EEV-HB0G221P

The EEV-HB0G221P has a number of features that make it particularly suitable for a wide range of applications. These features include a rated voltage of 250V and a maximum operating voltage of 630V, an extensive usable temperature range of -45°C to 85°C, a high frequency response of ≤ 0.5dB from 0.1 to 3GHz and a high power handling capability of up to 650W/kg. The extensive life expectancy of the EEV-HB0G221P is up to 10,000 hours at +105°C.

Applications of an EEV-HB0G221P

Due to its combination of excellent frequency response, extended life and high power handling, the EEV-HB0G221P capacitor is ideally suited to a range of applications, including power supplies, DC/DC converters and high-grade UPS systems. It is also routinely used in a wide range of industries, including consumer, medical, industrial and military applications. It is also frequently used in consumer electronic products, such as handheld medical devices, LED displays, LED drivers and LED light fixtures.

Working Principle of an EEV-HB0G221P

The working principle of the EEV-HB0G221P is based on the electrochemical principles of a capacitor. When a voltage is applied to the capacitor, ions from the electrolyte solution are attracted to the surface of the anode. This creates an electrolytic film on the anode, enabling the capacitor to store energy. When the applied voltage is removed, the ions return to the electrolyte solution and the stored energy is released.

In summary, the EEV-HB0G221P is a rectangular aluminum electrolytic capacitor with excellent frequency response, extended life and high power handling capabilities. It has a wide range of applications in the consumer, medical, industrial and military spheres, and is particularly suitable for use in power supplies, DC/DC converters and high-grade UPS systems. Its working principle is based on electrochemical principles, with ions from the electrolyte solution being attracted to the surface of the anode and forming an electrolytic film, enabling the capacitor to store energy and release it when the applied voltage is removed.
