Dielectric Types

Adding New Capacitor Patterns

1. In the manufacturer handler's initializePatterns():

registry.addPattern(ComponentType.CAPACITOR, "^NEWCAP[0-9]{4}.*");
registry.addPattern(ComponentType.CAPACITOR_CERAMIC_MANUFACTURER, "^NEWCAP[0-9]{4}.*");

1. 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
