Aluminum - Polymer capacitors are the latest development in capacitors technology, offering a unique combination of high capacitance density and low ESR values, while providing a smaller package size than traditional aluminum electrolytic capacitors. A typical application area of Aluminum - Polymer capacitors is power supplies and dc-to-dc converters, providing efficient energy storage and regulation in a variety of settings.The RUC0D271MLG capacitor is a high-performance aluminum-polymer capacitor developed and produced by Rubycon, an electronics component manufacturer. It is a highly integrated device, incorporating both the capacitor and placed components in a single package. The capacitor is designed for a wide variety of applications, such as power supplies, dc-dc converters, EMI filters and high-frequency circuits.The RUC0D271MLG capacitor is a 305-volt, 6.3mm x 10mm chip type device with rated capacitance of 270 microfarads. It has a rated ripple current up to 4 amps and a rated impedance of 0.29 ohms at 100KHz. It also features a rated ESR between 0.02 and 0.06 ohms, making it ideal for power supply applications.The working principle of the RUC0D271MLG is based on the concept of electrochemical double layer capacitor (EDLC), utilizing the unique combination of an ionic conductive polymer electrolyte and a highly conductive aluminum foil as electrodes. In EDLC capacitor technology, the anode and cathode of the device are separated by the dielectric polymer electrolyte, and the breakdown voltage is determined by the amount of charge required to polarize the electrolyte.The RUC0D271MLG capacitor also utilizes a high conductivity, low resistance aluminum foil as the positive and negative electrode. When a voltage is applied, the aluminum foil is polarized, resulting in an effective capacitance increase. The combination of the highly conductive aluminum foil, the high conductivity of the polymer electrolyte and the low external resistance offers the capacitor a high ripple current rating and improved ESR values compared to traditional aluminum electrolyte capacitors.In addition to the enhanced performance, the RUC0D271MLG capacitor also offers a number of design advantages. Its compact size allows for a highly integrated design, with a smaller footprint than conventional electrolytic capacitors. This leads to a lower total cost of parts and reduced board space, as well as improved thermal management.Overall, the RUC0D271MLG is an excellent choice for applications requiring high capacitance density and low ESR values, delivering excellent performance in power supplies and dc-to-dc converters. Its robust construction and innovative design make it a reliable and cost-effective solution for a wide range of applications.
