Aluminum electrolytic capacitors are a type of capacitor that uses an intense electrical field to cause a thin oxide film to form on the surface of a thin aluminum foil roll, creating a double-layer structure. The ALS80A272QC450 is a high capacity capacitor, with a trust current of 340mA(Ibed) and a rated voltage of 450VDC, that provides a reliable and stable performance in the commercial market.

The construction of the ALS80A272QC450 is based on a fitted plate-stacked mechanism equipped with a proprietary step-based separator technology. This allows the capacitor to provide high capacitance in a small volume. The device has a very low leakage current, making it suitable for high-frequency applications. The ALS80A272QC450 has a wide capacitance range of 4.7uF to 680uF, providing a wide range of capacitive values for different applications.

The ALS80A272QC450 is a surface-mount device used in the following applications:

• DC/DC converters
• Filtering and smoothing
• Power supply units
• Load balancing
• Motor drive circuits
• Power converters
• Switching power supplies
• Power input stages

The working principle of an aluminum electrolytic capacitor is based on the principles of electrostatics. As electricity passes through the capacitor, a thin layer of oxide forms on the aluminum foil that acts as a dielectric and stores charge in the capacitor. A thin aluminum foil is sandwiched between two layers of activated paper, which act as electrodes and conduct electricity. The electrodes and paper are saturated with ions, and charge is stored on the surface of the aluminum when electricity is applied.

The ALS80A272QC450 is also able to offer a high ripple current at 105°C. This is achieved due to a combination of a high capacitance, an electrolyte impregnation process, a large contact area, and a wide temperature range. Furthermore, the device has a reinforcing margin of more than 5 times compared to normal products in its class. It also has an insulation resistance of 100Mohm, which provides a high degree of reliability.

The ALS80A272QC450 is available in three different sizes: 6.3x13, 12.5x18, and 18x25. The device also features a proprietary encoder system, which enables easy storage and tracking for production and warranty purposes. In conclusion, the ALS80A272QC450 is a reliable and high-performance aluminum electrolytic capacitor and is suitable for a wide range of commercial applications.
