Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors use aluminum foil as electrodes, and use a layer of oxide film formed by anodizing electrolytic solution and intervening electrolyte. The anode aluminum oxide film and electrolyte constitute a capacitor, thereby forming a dielectric body capable of storing electric charge. Their main feature is that the capacitance can be large, but the equivalent series resistance (ESR) is high, and the self-healing ability is poor. Therefore, aluminum electrolytic capacitors are generally used as general-purpose, low-cost capacitors to filter or bypass signals.

UHA1E4R7MHD application field and working principle

UHA1E4R7MHD aluminum electrolytic capacitors are miniature, low cost and high performance electrolytic capacitors. It is a kind of radial molded type electrolytic capacitor. It is a ready-made aluminum electrolytic capacitor composed of aluminum foil and paper/polypropylene film dielectric material. With the development of modern industry, the use of UHA1E4R7MHD aluminum electrolytic capacitors is also getting wider and wider.

The working principle of UHA1E4R7MHD aluminum electrolytic capacitors can be roughly divided into four steps: coating, winding, impregnation, and low-frequency drying. First, a layer of solidified thin oxide film is formed on the surface of the aluminum foil by anodizing, and then the paper/polypropylene film is vertically wound around the aluminum foil. After the winding is completed, a layer of electrolyte is injected into the capacitor container, and then the capacitor is placed in a specific low-frequency oven for a drying process.

UHA1E4R7MHD aluminum electrolytic capacitors are mainly used in low-cost circuits where technical management is not required, such as low-frequency bypass, mid-range, decoupling, filtering, LCD backlight display, and radio clock power supplies. In addition, UHA1E4R7MHD aluminum electrolytic capacitors can also be found in some motor control circuits, such as servo motors, stepping motors, and induction motors.

UHA1E4R7MHD aluminum electrolytic capacitors have the characteristics of low cost, small size, light weight, large capacity, good insulation performance and good self-healing ability. In addition, compared with ordinary aluminum electrolytic capacitors, UHA1E4R7MHD aluminum electrolytic capacitors have better temperature characteristics. The operating temperature range of this type of capacitor is between -25 and +85 degrees Celsius.

In conclusion, UHA1E4R7MHD aluminum electrolytic capacitors can be widely used in various fields and are widely used because of their wide range of applications. It is an ideal electronic capacitor component with high cost performance and is the preferred capacitor component for many electronic equipment.
