Aluminum electrolytic capacitors, also known as aluminum electrolytic capacitors, are polarized capacitors with an etched aluminum oxide (aluminum oxide) film as the dielectric. It is widely used in many electronic applications as an energy reservoir due to its high capacitance and capacitance per unit volume. The model UPW1J391MHH6 is an aluminum electrolytic capacitor.

The UPW1J391MHH6 aluminum electrolytic capacitor is designed for high temperature applications, with a nominal capacitance range of 2.0 uF - 1 mF, and various factory-determined capacitance tolerances. Its highly reliable design permits a wide temperature range of -25°C to +125°C, and a corresponding ripple current range of 1.3 – 3.4 Amps. The UL94 V-0 flame retardant plastic case, combined with nickel over tin plating, ensures excellent heat dissipation.

UPW1J391MHH6 capacitor is suitable for application in various fields, such as power factor correction, high-frequency power factor correction, high-frequency filtering, inverter power supplies of plasma display, power supplies of automotive electronics, high-efficiency switching power supplies, uninterruptible power supplies, 3C products, and other electronic products. Its characteristics of high ripple current, reliable heat resistance, and excellent long-term stability are very conducive to these applications.

The UPW1J391MHH6 aluminum electrolytic capacitor operates on the principle of an induced electrical double layer within the thin insulating anodic dielectric oxide layer. This dielectric oxide layer acts as the energy storage element. A negatively charged electrode (the anode) and a positively charged electrode (the cathode) are positioned on either side of the dielectric layer, creating a two-electrode device. When an external voltage is applied, positive charge is held on one side of the dielectric layer and negative charge is held on the other side. The stored energy is directly proportional to the capacitor\'s capacitance. When the external voltage is applied, the capacitor supplies current from one of the electrodes to the other. The capacitor will maintain this state until the voltage is removed.

In conclusion, UPW1J391MHH6 is a high-temperature aluminum electrolytic capacitor, suitable for high temperature applications. It features good heat dissipation and reliable, long-term stability, and can be used for power factor correction, high-frequency power factor correction, high-frequency filtering, inverter power supplies of plasma display, power supplies of automotive electronics, high-efficiency switching power supplies, uninterruptible power supplies, and other 3C products. The internal mechanism is based on the principle of an induced electrical double layer, which stores energy in a dielectric oxide layer.
