Aluminum Electrolytic Capacitors (AECs) have been the standard capacitor mode for decades because of their high power density, low cost, long cycle life, and excellent performance. ULD2G2R2MPD6TA is one of the most popular AECs, widely used in various fields due to its excellent characteristics. This article introduces the application fields and working principle of ULD2G2R2MPD6TA.Application Fields of ULD2G2R2MPD6TAULD2G2R2MPD6TA is mainly used in the applications of signal-level filters and transducers, memory backup, regulator bypass, and AC line frequency filters.Signal-Level Filters and Transducers: ULD2G2R2MPD6TA features excellent stability even during the high frequency signals, making it an ideal choice for signal-level filters and transducers. Furthermore, its high energy storage capacity also allows various applications, like signal decoupling, impedance matching, and high frequency suppressing.Memory Backup: ULD2G2R2MPD6TA is also suitable for protecting memory information and calibrations for short-term power outages due to its low leak current, good heat dissipation, and long cycle life.Regulator Bypass: similar to the memory backup application, ULD2G2R2MPD6TA is ideal for regulator bypass for providing a stable source of energy.AC Line Frequency Filters: ULD2G2R2MPD6TA excels in suppressing AC line frequency noise, which makes it a great choice for AC line frequency filters.Working Principle of ULD2G2R2MPD6TAULD2G2R2MPD6TA is based on a three-layer construction. The top layer is made of aluminium foil, covered by a layer of an enzyme-impregnated paper, which serves as the dielectric layer. The bottom layer is made of aluminium foil, which is electrically connected to the electrolyte.When a voltage is applied between the two aluminium layers, an electric field is generated. This electric field affects the electrolyte and causes the ions (charged particles) to flow through the electrolyte, which in turn results in electric charges accumulating on the edges of the aluminium foils. This accumulation of electric charges creates a storage for the capacitor and determines its capacitance.At the same time, the electrolyte can provide a certain amount of resistance, which offers ESR (Equivalent Series Resistance). This ESR helps reduce the peak currents in the circuit and ensures optimal voltage stability.ConclusionULD2G2R2MPD6TA is one of the most popular aluminum electrolytic capacitors, used in various fields due to its high power density and excellent performance. It is mainly used in signal-level filters and transducers, memory backup, regulator bypass, and AC line frequency filters. This article introduces the application fields and working principle of ULD2G2R2MPD6TA.
