Overview of KEMET C512B Ceramic High Reliability Capacitors
KEMET Electronics Corporation is recognized as a leader in producing high reliability monolithic ceramic capacitors. These capacitors are known for their “State of the Art” performance, achieved through rigorous selection of materials, conservative design principles, comprehensive employee training, and meticulous inspection processes for both in-production and finished products.
Key Features & Basic Requirements
KEMET’s high reliability products, including the GR900 and MIL-PRF-123 series, adhere to strict military standards and feature:
- Selected Raw Materials: Utilization of top-quality raw materials with traceability maintained throughout the manufacturing process.
- Batch Homogeneity: Strict batch control ensuring homogeneity in terms of materials, design, and processing conditions.
- Clean Room Processing: Processes sensitive to particulate contamination are conducted in clean room environments.
- Special Designs: Enforcement of design considerations, such as dielectric thickness, tailored to each capacitor’s application.
Product Specifications & Testing
The C512B capacitors offer two temperature characteristics:
- COG (BP): Made from non-ferroelectric ceramics like BP indicating superior stability but lower packaging efficiency.
- XZR (BX): Made from ferroelectric materials such as barium titanate, BX provides stable performance with high packaging efficiency.
The capacitors are subject to several quality control and testing procedures, including:
- Destructive Physical Analysis (DPA): All batches are DPA sampled per EIA-469 standards, with reports and retained samples.
- C-SAM Screening: Optional 100% ultrasonic screening to detect voids or delaminations, with mandatory final sample DPA.
- Batch Performance Monitoring: Testing of production batches to generate electrical characteristics, with rejection of anomalous batches.
Special Processing & Customer Specifications
KEMET can accommodate special processing requirements, such as serialization, special packaging, and documenting customer-specific requirements into modified standard procedures.
All KEMET products follow a comprehensive Quality System supervised by the KEMET Quality Manual and Quality Operating Documents, ensuring strict compliance and revision control.
