Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are electrical components used to store energy, filter signals, and regulate voltage levels. They consist of two metal conductive plates separated by a thin insulating material, typically a paper or plastic spacer. The conducting plates are made of one of two materials, aluminum or tantalum, and often have an oxide layer on their surfaces. This layer ensures the capacitor’s electrical properties remain unchanged over time.

ALS70U562NP500

The ALS70U562NP500 aluminum electrolytic capacitor is manufactured by Panasonic. It is a radial-leaded, non-polarized capacitor with a rated temperature range of -55°C to +105°C. The capacitor features a capacitance of 0.68µF, a voltage rating of 16V, and a maximum ESR of 200mΩ. The device is suitable for reflow solder (excluding lead-free) and wave solder processes.

Application field and working principle

Aluminum electrolytic capacitors such as the ALS70U562NP500 are used in a variety of applications, including power supplies, motor drives, power back-up systems, alarm systems, and consumer electronics. They are ideal for use in high-frequency switch-mode power supplies due to their low ESR and high ripple current capacity.

The working principle of the ALS70U562NP500 is based on a process known as oxidation. Oxidation occurs when oxygen molecules attach to the aluminum surface, forming an oxide layer. This layer creates an electrical barrier between the two metal conductive plates, known as electrodes, in the capacitor. When a voltage is applied to the capacitor, a charge accumulates at the oxide layer, and electrical energy is stored. The amount of energy stored in a capacitor is determined by its capacitance, which is measured in Farads. The ALS70U562NP500 has a capacitance of 0.68µF, indicating it can store 0.68 micro-coulombs of energy.

Aluminum electrolytic capacitors are a cost-effective and reliable technology, offering high capacitance values, long life, and low impedance characteristics. The ALS70U562NP500 is designed to be used in a variety of applications and is capable of withstanding extreme temperatures.
