UPA1V391MPD6TD Capacitors

Aluminum Electrolytic Capacitors

The UPA1V391MDP6TD is a type of aluminum electrolytic capacitor, one of a series of such capacitors produced by Nichicon. An aluminum electrolytic capacitor is an electronic component allowing capacitance, produced by the combination of aluminum foil, a separator soaked electrolyte, and a layer of electrolytic paste on the aluminum foil, which is the core of the electrolytic capacitor.

Application Field

UPA1V391MDP6TD aluminum electrolytic capacitors are ideal for use in high-frequency, high-temperature and low-impedance circuits, particularly in audio systems and power supplies. They are popularly used in consumer electronics such as TVs, computers, musical equipment, and robotics. Because of their high-temperature and low-impedance capabilities, UPA1V391MDP6TD aluminum electrolytic capacitors can also be used in automotive and other industrial applications.

Working Principle

An aluminum electrolytic capacitor consists of an anode foil and a cathode, which are placed in the electrolyte solution and subjected to electrochemical oxidation and reduction. When a voltage is applied to the external terminals, positive and negative ions merge on mutually opposite electrodes under the action of electric current. An electrode reaction produces dopants in the active material, which form a dielectric layer on the surface of the anode to increase the capacitance of the anode. Thus, the capacitance of an electrolytic capacitor is determined by its anode diameter, thickness, electrolyte solution, foil choice, and so on.

UPA1V391MDP6TD aluminum electrolytic capacitors are recognized for their ability to withstand high frequency and temperature as well as their low loss and low stray capacity. They also have a long life span and can operate for up to 10,000 hours at temperatures of up to 105°C.

The UPA1V391MDP6TD aluminum electrolytic capacitor is a special type of capacitor that has been designed to meet the professional and industrial needs of the modern market. Its high- capabilities, long life span, and low price make it an attractive choice for many applications.
