Dielectric Types
| Code | Type | Temp Range | Capacitance Change |
|---|---|---|---|
| C0G/NP0 | Class I | -55°C to +125°C | ±30ppm/°C |
| X7R | Class II | -55°C to +125°C | ±15% |
| X5R | Class II | -55°C to +85°C | ±15% |
| Y5V | Class II | -30°C to +85°C | +22%/-82% |
Adding New Capacitor Patterns
- In the manufacturer handler's
initializePatterns():
registry.addPattern(ComponentType.CAPACITOR, "^NEWCAP[0-9]{4}.*");
registry.addPattern(ComponentType.CAPACITOR_CERAMIC_MANUFACTURER, "^NEWCAP[0-9]{4}.*");
- Add to
getSupportedTypes():
types.add(ComponentType.CAPACITOR);
types.add(ComponentType.CAPACITOR_CERAMIC_MANUFACTURER);
Similarity Calculation
CapacitorSimilarityCalculator compares:
- Capacitance value
- Voltage rating
- Dielectric type (C0G, X7R, X5R, etc.)
- Package size
- Tolerance
