ECAS Polymer Aluminum Electrolytic Capacitors

Murata ECAS Polymer Aluminum Electrolytic Capacitors offer low equivalent series resistance (ESR) of 4.5mΩ to 40mΩ and high capacitance of 15µF to 470µF with rated voltages from 2V_DC to 25V_DC. In addition to low ESR and large capacitance, the ECAS series features low impedance and no DC bias characteristic of capacitance and stable temperature characteristics. These capacitors are constructed with a resin-molded structure, multilayer aluminum foil for the anode, and a solid conductive polymer for the cathode. These polymer aluminum electrolytic capacitors (ECAS) exhibit strong ESR performance compared to traditional electrolytic capacitors and provide similar characteristics compared to multilayer ceramic capacitors (MLCCs). The ECAS line also provides good temperature characteristics, no need for voltage derating, and resistance to short circuits.
