Engineering review checklist
- Verify capacitance tolerance, rated voltage, temperature range and any DC-bias derating.
- Check ESR, ripple-current capability, lifetime and polarity requirements under worst-case conditions.
- Confirm package dimensions, land pattern and reflow or mounting limits for the selected ordering code.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
