Aluminum electrolytic capacitors are a type of capacitor that utilize a thin layer of anodic aluminum oxide as the dielectric and two aluminum foils coated with an electrolyte as the electrical conductivity. The two aluminum foils, commonly referred to as anode and cathode, act like a separator for the current as it passes through the capacitor. UPM1E391MHD6TO aluminum electrolytic capacitor is specifically designed for high-precision applications with long standby time and long life. It is capable of storing a load of up to 91 μF, and can hold a maximum operating voltage of 170 VDC.

Unlike other types of capacitors, like ceramic, tantalum, or film capacitors, aluminum electrolytic capacitors are constructed in rectangular cases with leads. The bodies of aluminum electrolytic capacitors are usually made from aluminum. This helps to keep the overall size and weight low, while drastically lowering the price of the part. This is because aluminum is easily extruded and stamped, resulting in a product that has a surprisingly low cost.

UPM1E391MHD6TO aluminum electrolytic capacitors provides users with a phenomenal level of precision and high reliability, thanks to the optimized electrolyte recipe and micro-mechanically made, low-ESR, aluminum-foil electrodes. In addition to its high performance, this type of capacitor is also capable of providing very long life, up to 20,000 hours, even with its low-priced structure.

The UPM1E391MHD6TO aluminum electrolytic capacitor is widely used to store energy in a wide variety of electronic systems due to its extremely low ESR and high capacitance. It is suitable for high-power circuits, such as motor drive circuits, or any circuits that require high current and low resistance. It is also used in various audio applications and for powering LEDs.

The working principle of this aluminum electrolytic capacitor is quite straightforward. It works by having a layer of aluminum oxide dielectric between the anode and cathode. The anode and cathode are connected to the voltage source, and when electric power is supplied, an electric field is created between them. This electric field is strong enough to break down the oxide layer, allowing current to flow. At the same time, the electric field causes electrons to move from the anode to the cathode and vice-versa, pouring a charge onto the plates and creating a potential difference.

When the current stops flowing and the electric field collapses, the electric charge built up on the plates is stored by the capacitor until the voltage across the plates is increased once more. This working principle makes aluminum electrolytic capacitors capable of storing energy from DC, such as from low-level battery circuits, or from AC, such as from audio amplifiers. Owing to its long life, high stability, and low resistance, UPM1E391MHD6TO aluminum electrolytic capacitors are highly reliable components for all sorts of energy storage applications.
