Selection Notes
- Select by the parameter limits in the table, then confirm the derating curves in the full specification before committing a design.
- Package and footprint dimensions are listed per part. Verify against your land pattern — the same series can ship in several case sizes.
- Where the series spans automotive and consumer grades, check the part number suffix. The electrical values may match while the qualification does not.
Common Questions
How many part numbers are in the ECAS series?
45. The table above lists every one, sorted by part number.
What do the parts in the ECAS series have in common?
They share the same polymer aluminum electrolytic capacitor construction and case-size family; the differences are the electrical values shown per row.
Where can I find the full specification for a ECAS part?
Each part number links to Murata's official product page, which carries the detailed specification sheet, reliability data and simulation models.
