The ECAS series Polymer Aluminum capacitors are a resin molded case structure that utilizes multilayer aluminum foil for the anode and solid conductive polymer for the cathode, making this a polarity sensitive product. The current capacitance range is 6.8µF to 470µF with a rated voltage of 2V to 25V. Its ESR is 4.5 mΩ to 70 mΩ and has an operating temperature range of -55°C to 125°C. Furthermore, unlike high dielectric type ceramic capacitors, it has no acoustic noise, and its capacitance is stable with applied DC bias and temperature.
