Aluminum-Polymer CapacitorsAluminum-polymer capacitors are a type of capacitor that provides capacitance and stable electrical performance even in harsh environments. They are made up of two aluminum foil plates separated by a dielectric material such as polypropylene. These capacitors are particularly useful for applications that require high levels of capacitance in low temperatures such as in low power supplies, automotive electronics, and home appliances.EEF-UD0D471LR is an aluminum-polymer capacitor developed by Mingte Technology. It is characterized by a direct current leakage of 0.001 μA or lower, high capacitance stability under temperature, and a long lifespan. These features make the EEF-UD0D471LR an ideal choice for a wide range of applications including signal isolation and power saving.EEF-UD0D471LR Application FieldThe EEF-UD0D471LR is ideal for applications in signal isolation, power saving, radiation shielding, and noise filtering. It can also be used in pulse width modulation, DC-DC converters, converters, LED dimmers, and switch drivers.The EEF-UD0D471LR is also well suited for use as a voltage regulator since it is able to provide stable voltage over a wide temperature range and can handle high input voltages. This makes it an ideal choice for high temperature applications such as in automotive electronics and home appliances.EEF-UD0D471LR Working PrincipleThe EEF-UD0D471LR works based on the principle of a capacitor where two metallic plates are separated by a thin dielectric material such as polypropylene. When a voltage is applied across the capacitor, electrons flow onto the negative plate while ions flow onto the positive plate. This creates an electric field between the two plates that stores energy.The capacitance of the EEF-UD0D471LR is determined by the size of the plates and the thickness of the dielectric. Together, the plates and the dielectric create a dielectric barrier that prevents electron leakage and provides an efficient path for the electrons to flow.ConclusionThe EEF-UD0D471LR aluminum-polymer capacitor is a reliable and efficient capacitor designed for a wide range of applications. Its high temperature and input voltage performance, combined with its excellent low current leakage, makes it an ideal choice for signal isolation, power saving, and other high temperature and power applications. Its robust design ensures a long life and consistent performance under even the harshest environmental conditions.
