Aluminum Electrolytic Capacitors: 63ZLJ560M12.5X30

What Is It?

Aluminum electrolytic capacitors (also known as Al / EL or simply EL) are capacitors in which the electrical energy is stored in a thin layer of aluminum oxide that acts as the dielectric. This layer is formed on an aluminum or tantalum foil that acts as the anode, with a liquid electrolyte or solid polymer electrolyte that acts as the cathode, resulting in a non-polar capacitor. Aluminum electrolytic capacitors are typically polarized, which means that they can only tolerate the applied voltages in one direction, and are therefore used in circuits with DC supply.

Application Field and Working Principle

The application field of 63ZLJ560M12.5X30 aluminum electrolytic capacitors includes motor drive circuits and switching power supply circuits, with working voltages from 6.3 to 450V and capacitance values from 4.7 to 100,000uF. This type of capacitor is specifically designed for high frequency pulse current signal, high ripple current and high temperature applications. The working principle of aluminum electrolytic capacitors can be explained by their structure: the anode and cathode are separated by aluminum oxide which acts as an electric field to store energy. When an electric voltage is applied, an electrical field will be formed between the plates. The electric field pulls electrons onto the anode, which increases the charge on the plate. This charge produces an opposing field on the plate and electric current begins to flow. The high temperature and frequency pulse current applications of aluminum electrolytic capacitors require a stable oxide layer on the anode that can withstand high temperatures. The oxide layer is formed when the anode is immersed in the electrolyte solution, which is usually made from sulfuric acid, phosphoric acid or ammonium bicarbonate. This layer is formed through an electrolytic process, during which the dielectric material is electrochemically produced from the positive ions of the electrolyte solution. The electric field between the two electrodes produces an electric current, which is stored as potential energy in the capacitance between the anode and cathode. This change in capacitance results in an actual change in voltage, a phenomenon known as “charging”. The stored charge can then be discharged rapidly when required, releasing an energy spike when needed. In essence, 63ZLJ560M12.5X30 aluminum electrolytic capacitors provide a reliable, cost-effective storage solution for motor drive and switching power supply circuits. The stable oxide layer, combined with their ability to store and rapidly discharge electrical energy, makes them the perfect solution for these applications.
