UPM2A391MHD

Aluminum electrolytic capacitors are common in electronic components. They are characterized by high capacity and low cost. The UPM2A391MHD (MicroFarads, 39V DC)is one type of aluminum electrolytic capacitor, and its application field and working principle are as follows:

Application field

The UPM2A391MHD is a through-hole mounting type aluminum electrolytic capacitor. It is suitable for a wide range of applications such as consumer electronics, power supplies, industrial equipment, automotive, computers and other digital equipment. Its wide operating temperature range allows it to be used in a variety of environments and its long life and high reliability make it ideal for these applications.

Working principle

The UPM2A391MHD aluminum electrolytic capacitor is composed of aluminum foil, electrolyte, and a non-conductive material separating the aluminum and electrolyte. When the capacitor is energized, the aluminum and electrolyte form the dielectric layer, creating a particular capacitance. As the capacitor is charged and discharged, ions move between the anode and cathode, resulting in changes in capacitance. This is the same process for all aluminum electrolytic capacitors.

The UPM2A391MHD features an etched anode foil, making it ideal for both low-resonance/low-ESR applications and noise sensitive environments. Its low impedance and high capacitance makes it ideal for applications such as boosting efficiency and power filtering. Its high reliability makes it ideal for both consumer and commercial applications.

In summary, UPM2A391MHD aluminum electrolytic capacitors are used in a wide variety of applications in numerous industries. They are low cost, have a wide temperature range, excellent reliability, high capacitance, and low impedance.
