Polymer Aluminum Electrolytic Capacitors -ECAS Series-
Murata’s Polymer Aluminum Electrolytic Capacitors(ECAS Series) has the feature of large scale, low ESR, and low impedance.
ECAS Series is widely applied to product power circuits.
For example, it is applied in laptop PCs, servers, accelerators, HDDs, panels, industrial PCs as well as LCD TVs, game consoles, networks, etc.
Large capacity
The ECAS series is higher in capacity compared to MLCC and have no voltage dependences. Therefore, they can be used to reduce the number of components and miniaturize the set for applications that use several MLCCs.
| Item | Total effective capacitance @ 12V | Qty. | Total area |
|---|---|---|---|
| ECAS 100μF/16V | 100 | 1 | 31.39 |
| MLCC 47μF/16V | 99 | 9 | 72 |
Low ESR
The ECAS series possesses a stable reliability compared to Ta capacitors, contributing to stable operations on products that have adopted them.
Low impedance
The ECAS series with its large capacitance characteristics features excellent stability with respect to load-side fluctuations in large-current applications.
