Aluminum electrolytic capacitors use a chemical reaction between aluminum foil and electrolytic paper (containing a liquid electrolyte) to create a charge. The most common form of an aluminum electrolytic capacitor is a cylindrical two-terminal device with a screw or snap-in mounting. The charge and discharge of the voltage on the capacitor is accomplished by the absorption and desorption of the electrolyte.The ELBK250ELL422AL20S is a grade A aluminum electrolytic capacitor with dual-side welding with a voltage of 2.2 VDC. This aluminum electrolytic capacitor has a rated voltage of 250 VDC, a capacitance of 4200μF, and a maximum ripple current of 12.2A (115C / 2000Hz). Its application is best suited in 250VAC / DC, inverter circuits, CRT circuits and other general-purpose applications.The ELBK250ELL422AL20S aluminum electrolytic capacitor is most suitable for high volume and low-cost applications, but it should not be used in applications that require high voltage or high ripple current. The capacitor is highly stable and has a long service life, with an operating temperature range of -40°C to +105°C.The working principle of the ELBK250ELL422AL20S aluminum electrolytic capacitor is that it stores energy as an electrical field. A capacitor stores electrical energy in an electrical field, which is created by positive and negatively charged electrical particles and the material between them. The aluminum electrolytic capacitor is made up of two alternating layers of aluminum foils and electrolytic paper. The aluminum foil is exposed to a chemical (such as water or liquid electrolyte) in the electrolytic paper, which creates a chemical reaction. This reaction causes the negative charges present in the electrolytic paper to be absorbed by the aluminum foil. The electrical charges in the electrolytic paper are attracted by the oppositely charged foil and accumulate there, thus producing an electrical field. This electric field is maintained even when there is no current, allowing the capacitor to store energy and provide power when required.The ELBK250ELL422AL20S aluminum electrolytic capacitor is a reliable and cost-effective capacitor, which is suitable for applications such as 250VAC / DC, inverter circuits, CRT circuits and other general purpose applications. The capacitor also has a long service life and can operate in temperatures as low as -40°C. The capacitor is rated at 250 VDC, 4200μF, and 12.2A (115C / 2000Hz), and is best suited for high volume and low cost applications.
