Aluminum electrolytic capacitors are one of the most widely used capacitor types due to their high capacitance, good robustness and low cost. The ALS80U752NJ350 is a type of aluminum electrolytic capacitor that features a low ESR, high ripple current, low leakage current and long life characteristics. Although its nominal capacity is only 80μF, it is typically used in applications that require a higher capacitance. It is commonly used in DC-DC converters, power supplies, LCD/LED/TV displays, and other electrical components.

Application Field

The ALS80U752NJ350 is most commonly used in DC-DC converters. It is well-suited for high-current, continuously switching circuits that require frequent current reversals. Its combination of low ESR and high ripple current capabilities makes it an ideal choice for these applications. Additionally, its small size allows it to be used in portable devices that require a compact and lightweight capacitor.

The ALS80U752NJ350 is also commonly used in power supplies and LCD/LED/TV displays. It effectively filters voltage fluctuations in power supplies that contain varying levels of voltage and current, resulting in a more stable output. It is also used in LCD/LED/TV displays to provide a constant voltage supply, resulting in a crisper and clearer picture quality. Additionally, it can be used in other electrical components such as motor control circuits and sensors.

Working Principle

At the core of the ALS80U752NJ350 is a metalized aluminum-foil electrode that is insulated by a ceramic dielectric. The aluminum terminal, or anode, of the capacitor is connected to a power supply or other load, while the other terminal, or cathode, is connected to the ground. When a voltage is applied, electrons are pulled from the anode and are attracted to the particles of the dielectric material, creating an electrical field. This field stores the electrical energy and, when a current is applied, releases it back into the circuit.

The capacitor is designed to provide an excellent combination of low ESR, high ripple current, low leakage current and long life. It relies on dielectric absorption and the forming process to create the low ESR. This allows the capacitor to effectively handle high wattage applications with minimal power loss. Meanwhile, its high ripple current allows it to handle frequent current reversals and dynamic loads without experiencing significant voltage drops. Additionally, its low leakage current ensures that a consistent voltage supply is maintained, creating a clearer and more reliable output.

The ALS80U752NJ350 is an advanced aluminum electrolytic capacitor that is suited for use in high-current and dynamic load applications. Its combination of low ESR, high ripple current, low leakage current and long life make it an excellent choice for applications such as DC-DC converters, power supplies and LCD/LED/TV displays.
