Aluminum - polymer capacitors are a type of electrolytic capacitor consisting of two electrodes: one made of aluminum (the anode) and the other made of a conductive polymer (the cathode). The electrodes are separated by an ionic electrolyte, usually an aqueous solution. These capacitors are popular in a wide range of applications due to their high capacitance and low ESR. The capacitance range for aluminum - polymer capacitors is typically between 1µF and 220µF, depending on the type of capacitor and size of the electrodes.The APXD100ARA470ME61G is an aluminum - polymer capacitor from Murata, with a capacitance of 100µF and a rating of 4.7V. It has a high capacitance and low ESR, making it suitable for a wide variety of applications. Some common applications of the APXD100ARA470ME61G include audio and power supplies, DC-DC converters, output filtering, and frequency inverters.The working principle of aluminum - polymer capacitors is based on the Faraday law of electrolysis. The aluminum anode is the positive electrode, while the conductive polymer cathode is the negative electrode. Electrons flow from the anode to the cathode through the electrolyte, followed by an ionic current of ions from the anode to the cathode. As current flows between the electrodes, a voltage is created, which provides the capacitive effect.In terms of design, aluminum - polymer capacitors are much smaller than conventional electrolytic capacitors. This is because they use a thin layer of organic electrolyte on top of the aluminum anode to create capacitance instead of relying on a porous material like paper or rubber. In addition, they can work with a wide range of voltages and temperatures, making them very versatile in applications.The APXD100ARA470ME61G offers excellent performance and reliability. It is RoHS compliant and UL rated, making it safe to use in an industrial environment. It offers excellent noise suppression, making it well suited for audio applications.
