In summary, Murata’s advanced ECAS series of polymer aluminum capacitors provides numerous design benefits over tantalum capacitors. Aluminum is not subject to the same supply, lead time and pricing issues as tantalum, the ECAS series offers stability in these areas. The ECAS series is available in a wide range of tantalum replacement options, but also offers some performance advantages over other capacitor solutions, such as no acoustic noise effects which other types of capacitors are susceptible to. In addition, industry standard D (7343) case size and land pattern allow for drop-in tantalum replacement. Unlike tantalum capacitors, voltage de-rating is not required for polymer aluminum capacitors due to its forming voltage. The ECAS series also provides lower ESR due to its multilayer and conductive polymer structure. And because of this low ESR, the ECAS series also has lower impedance which provides better noise suppression and good ripple absorption. Additionally, unlike MLCC replacement options polymer aluminum capacitors offer stable capacitance and do not exhibit DC bias characteristics. And the ECAS series polymer aluminum capacitors provide excellent reliability and feature an electrochemical self-repairing characteristic. Lastly, the ECAS series has a benign failure mode for short circuit failure as compared to conventional manganese dioxide tantalum type capacitors in that they will not burn or explode. With these benefits the ECAS series offers an excellent replacement over tantalum type capacitors providing customers alternative solutions for reduced costs and improved designs.
