It is widely used in various electronic circuits, such as radio, stereo, television, computer, communication systems, power equipment and instrumentation.

Working principle

As an electrolytic capacitor, the working principle of the LGY1J682MELB50 is based on an electrolytic process, which involves using electrolytic solutions to absorb and release ions associated with electric current. In this process, aluminum oxide layers acting as dielectric layers are formed on the electrodes of the aluminum foils, which are usually anodized to increase the transistor dielectric strength. This process is required for capacitors to generate electrical energy storage, and LGY1J682MELB50 is a typical electrolytic capacitor.

The working principle of LGY1J682MELB50 is mainly determined by three parts: the anode film, the electrolyte and the cathode current collector. The anode film acts as a insulating layer, the electrolyte provides ion movement, and the cathode current collector helps to increase the capacitance. In addition to these, LGY1J682MELB50 also has a dielectric layer that isolates the anode and the cathode, thus allowing electrons to pass between them without flow.

When electrons flow into LGY1J682MELB50, they are positively charged and attracted to the negative terminal of the capacitor, while the positively charged ions are attracted to the anode, where they are then pulled into the electrolyte to neutralize the charge. The capacitance of an electrolytic capacitor is determined by its anode-cathode spacing, plus the thickness of the oxide layer. As the current pulses through the capacitor, the oxide layer generates an electric field that stores energy within its capacitance.
