Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor, also known as an aluminum electro or an elna capacitor, is an electrical component composed of two aluminum foils separated by a layer of paper or other thin insulation and soaked in electrolyte solution. Electrolytic capacitors are also used for their very high capacitance, which can range from a few microfarads to hundreds of microfarads.

UPW1H391MHD1TO Application Field and Working Principle

UPW1H391MHD1TO aluminum electrolytic capacitors are designed for high-end audio applications that require a low noise level. These capacitors are typically used in power supplies, preamplifiers, and other audio-related circuits. They are also often used as coupling capacitors, filtering capacitors, or ground bypass capacitors in a wide variety of other applications.

The UPW1H391MHD1TO aluminum electrolytic capacitor works by sandwiching an electrolytic material between two aluminum foils. When the capacitor is charged, the aluminum acts as the cathode and the electrolyte becomes the anode. The electrolytic material forms a series of tiny holes or pores through which electrical current can flow. The size of the holes determines the capacitance of the capacitor. As the capacitor is charged and discharged, the electrolytic material expands and contracts, causing the capacitance to change accordingly.

The UPW1H391MHD1TO aluminum electrolytic capacitor has a very low ESR (Equivalent Series Resistance) and ESL (Equivalent Series Inductance). This allows the capacitor to handle very high frequencies, making it suitable for audio applications. It has a wide operating range of -25°C to 125°C and can handle up to 2000V DC.

The UPW1H391MHD1TO aluminum electrolytic capacitor is an ideal choice for high-end audio applications requiring low noise and a wide operating range. With an incredibly low ESR and ESL, this capacitor offers high performance and reliability for even the most demanding applications.
