Aluminum electrolytic capacitors are widely used in a variety of industries due to their low cost, high capacity, and good energy storage capability. B41252B4189M is a type of aluminium electrolytic capacitor recently developed by a leading manufacturer in the industry, combining the advantages of high breakdown voltage, high ripple current and long service life for use in challenging applications.

B41252B4189M is designed for high temperature, long-term operation with a maximum working temperature of 105℃. It has an operating voltage range of 6.3 VDC to 25 VDC, a capacitance of 4.7μF to 680μF and a temperature coefficient of less than 15%. Its temperature stability, low internal resistance and high ripple current allow it to be used in a variety of demanding environments, including high frequency inverters, switching power supplies, automotive ignition systems, heavy-duty motors and automobiles.

In terms of its construction, B41252B4189M consists of an anode and a cathode formed from aluminium oxide, separated by an electrolyte solution. An electrical current passes through the electrolyte solution, creating an electrostatic field between the cathode and the anode. This electrostatic field stores electrical energy, which is eventually released when the capacitor is discharged. During usage, the capacitor has an initial leakage current caused by the electrolyte, which decreases steadily as it reaches equilibrium with the ambient environment.

The working principle of B41252B4189M is simple and effective. When an AC voltage is applied, a current flows through its internal electrodes, forming a capacitor. This capacitor then stores the energy from the voltage source and release it when the voltage source is no longer present. As the current passes through its internal electrodes, a voltage is built across its terminals, resulting in the capacitor becoming charged. Subsequently, when the voltage is no longer present, the capacitor discharges, releasing the stored energy. This process is repeated each time an AC voltage is applied.

The wide range of operational parameters makes B41252B4189M an ideal choice for various aluminum electrolytic capacitor applications. Its leakage current is low enough to be used in critical applications that require an extremely low ESR at low temperature. It also has a high ripple current rating, making it suitable for demanding high frequency circuits. Finally, its excellent temperature stability makes it suitable for use in applications with heavy-duty motors or automobiles.

Overall, B41252B4189M is a new type of aluminium electrolytic capacitor that combines the advantages of high breakdown voltage, high ripple current and long service life, making it an ideal choice for critical and demanding applications. Its construction, working principle, wide range of operational parameters, and ability to be used in heavy-duty applications make it a highly reliable and cost-effective solution for those in search of an aluminum electrolytic capacitor.
