Murata Polymer Aluminum Electrolytic Capacitors
ECAS Series

Murata offers the ECAS Series Polymer Aluminum Electrolytic Capacitors for low ESR , high capacitance areas. This ECAS series has a resin molded structure, utilizing multilayer aluminum foil for anode, and solid conductive polymer for cathode. The Murata line also features high capacitance (6.8µF to 470µF with rated voltages from 2VDC to 16VDC), low ESR (6 to 70 mohms), good temperature characteristics, no need for voltage derating, and resistance to short circuits. In addition, the Murata ECAS series Polymer Aluminum Electrolytic Capacitors are available in a case size of 7.3mm x 4.3mm with three different thickness options.

Murata ECAS Polymer Capacitor


Applications
  • Computer
  • Digital audio/visual
  • Telecom
  • Overall power management

Murata Electronics ' new series of polymer aluminum electrolytic capacitors ( ECAS Series) exhibit strong equivalent series resistance ( ESR ) performance compared to traditional electrolytic capacitors and provide similar characteristics when compared to multi - layer ceramic capacitors ( MLCCs ). The ECAS series allows Murata to greatly expand its high capacitance offerings, giving customers a full range of capacitor solutions.

The Murata ECAS series has a resin molded case structure, which utilizes multilayer aluminum foil for anode and solid conductive polymer for negative cathode. This surface mount design can be soldered using traditional reflow methods. The offered capacitance range is 6.8uF to 470uF with rated voltages from 2VDC to 16VDC. It is available in a case size of 7.3mm x 4.3mm with three different thickness options. The high capacitance value and low ESR lead to low impedance at high frequency (up to 500kHz). This provides excellent noise suppression, ripple absorption and decoupling abilities on power lines. In addition, the ECAS series offers capacitance stability at high operating frequencies and temperatures. Unlike MLCC 's, these capacitors do not exhibit drop with applied DC voltage. The operating temperature range is -40 to +105ºC, and all are RoHS compliant.
