Technical Guide Product Guide POLYMER Aluminum Electrolytic Capacitors ECAS Series www.murataamericas.com/polymer alPolymer Aluminum Electrolytic Capacitors Murata Manufacturing Co., Ltd.s ECAS series of polymer aluminum electrolytic capacitors realize low ESR, low impedence and high capacitance by means of multilayered aluminum foil for anode, solid conductive polymer for cathode. With no bias characteristics and stable temperature characteristics, ECAS series have excellent performance in ripple absorption, smoothing and transient response suitable for numerous applications. Therefore, it is suitable for smoothing of input-output current of various power supply circuits, and the backup use over the load change of the CPU circumference. This contributes to a reduction of the number of parts, or reduction of substrate area.
