In addition to the Automotive, MIL-PRF, and Space grade series, these are the Kemet proposals to address High Reliability Applications as a high reliability alternative.
CERAMICS COTS:
CXXXXT X7R series
CXXXXT COG series
Features:
- Higher Reliability Applications
- High CVs (close to Commercial and Automotive)
- Much lower volumes than Commercial and Automotive
- Slightly Lower Cost vs Military Grade
Qualification – By manufacturer. KEMET’s COTS based on AEC-Q200
Base Testing Protocol + Additions (Testing levels A, B or C):
- 100% Visual Inspection
- Burn-in, Voltage conditioning with PDA
- Electricals with PDA
- Destructive Physical Analysis (DPA)
- Humidity TestingCustomizable with drawing
Applications: higher reliability applications
CERAMIC HRA SERIES (under development)
Features:
- Conservative offering vs COTS and Auto Grade
- Higher CVs not available in MIL-PRF
- Auto Grade designs
- Customizable using SCD/C-SPEC
Qualification and Testing – Internal: References Automotive AEC-Q200 and MIL-PRF-32535 TM
Additional:
- Group A and B per MIL-PRF-32535
- Periodic inspection for electrical, environmental, and mechanical
- Test Summaries and CoC
- Complete material traceability to raw materials
Applications: Short duration or limited life, i.e. satellites (<5 Years), Launch Vehicles, Avionics, ground systems.
TANTALUM POLYMER HRA SERIES T540/T541
Features:
