Aluminum Electrolytic Capacitors (AECs) are a type of capacitor used in electronic circuits for various applications such as power supplies, filtering, and signal conditioning. The UPW1J390MED capacitor is a solid, reliable, and cost-effective AEC, which is widely used in a variety of applications. This article aims to provide a detailed description of the UPW1J390MED capacitor, its various application fields, and its working principle.The UPW1J390MED is a radial, single-layer, non-polarized, and electrolytic aluminum capacitor designed for use in circuits that require low ESR and low inductance. This capacitor has a rated capacitance of 100µF ±20 percent (at 25°C) and a rated working voltage of 10V. It is typically used in circuits that require an IDC (inrush current limit) rating of 2A or lower. The UPW1J390MED measures only 17.5mm x 10mm x 4.5mm, making it an extremely compact AEC.The UPW1J390MED capacitor is made up of an anode, cathode, and electrolyte, all housed within an aluminum canister. The capacitor uses a solid electrolyte with an anode foil that is formed into a “zig-zag” hexagonal pattern to maximize the surface area of the anode. The cathode is formed from a porous thermal paper saturated with a liquid electrolyte and is connected directly to the negative terminal of the capacitor.The UPW1J390MED capacitor is capable of handling a wide variety of applications, including motor controllers, power supplies, filter circuits, and audio applications. It is ideal for circuits that require an extremely small footprint and high capacitance in a limited space. Additionally, this capacitor has the ability to tolerate high ripple current and is capable of withstanding high humidity levels and vibration.The UPW1J390MED capacitor works according to the principle of electrophoresis, a phenomenon in which electrical energy is used to move ions from one side of a conductive material to another. Electrophoresis is enabled by an external voltage source, causing the anode and cathode to attract opposite charges. The resulting current flow creates an electrostatic field, which causes a separation of charges within the electrolyte solution. This movement of ions creates a charge imbalance at the electrodes, which is then stored in the dielectric material (the electrolyte) between the electrodes, thus producing the desired capacitance.In conclusion, the UPW1J390MED capacitor is a highly versatile and reliable aluminum electrolytic capacitor. Its small size and high capacitance make it ideal for a variety of applications, including motor controllers, power supplies, filter circuits, and audio applications. The UPW1J390MED capacitor works according to the principle of electrophoresis, which uses electrical energy to produce a charge imbalance in the electrolyte that is stored in the dielectric material between the electrodes, thus producing its desired capacitance.
