Aluminium polymer capacitor offers high capacitance and low ESR
The Murata ECAS series of polymer aluminium electrolytic capacitors, available from RS Components, realise low ESR, low impedance and high capacitance using multilayered aluminium foil for anode, solid conductive polymer for cathode.
With no bias characteristics and stable temperature characteristics, the series have great performance in ripple absorption, smoothing and transient response ideal for many applications. Accordingly, it is ideal for smoothing of input-output current of various power supply circuits, and the backup use over the load change of the CPU circumference. This adds to reduction of the number of parts, or reduction of substrate area.
