Aluminum electrolytic capacitors are a type of capacitor that is used in consumer and industrial electronics. They are made of two aluminum foils that are separated by an ionic “jelly” dielectric material. The first aluminum foil is kept positive with a layer of special electrolyte, while a rivet is used to attach the second aluminum foil, held negative by contact with the electrolyte. The contact between the foils also creates a layer of oxidized metal which serves as an additional insulator.

The UPZ2D391MHD aluminum electrolytic capacitor is a radial-leaded, non-polarized aluminum capacitor with a case size of 8.2mm x 15mm. This capacitor has a rated voltage of 50 volts and a capacitance of 391μF at 1kHz, with a temperature range of -55Supplied in a bulk package, it is suitable for many consumer and industrial applications. This capacitor also features up to 85% lower Equivalent Series Resistance (ESR) than other capacitors.

The UPZ2D391MHD is mainly used in power supply, switching power supply, LED lighting and automotive electronics. In LED lighting, they are used as a source of power smoothing, and in automotive electronics, they are used help power electronic control systems. It is a high-performance capacitor that helps stabilize voltage in power systems. It also helps suppress interference caused by switching and higher frequencies, improving the overall efficiency of the system.

The working principle of aluminum electrolytic capacitors is simple. Whenever an electric voltage is applied across its terminals, the metal plates respond by two-way separation. This is carried out by the electrolyte, which has ions that are attracted to the electrical current. The ions, in turn, form an isosceles triangle (in this case, three) within the electrolyte and act as the insulating material.

The UPZ2D391MHD aluminum electrolytic capacitor is a reliable and durable component, offering smooth operation and stable voltage regulation. It also has a long life span of up to 10,000 hours of continuous use. Its performance is largely unaffected by moisture, vibration and shock, and its low ESR provides better power handling and greater efficiency, making it suitable for a variety of high-performance electronics.
