In the manufacturer handler's `initializePatterns()`: ```java registry.addPattern(ComponentType.OPAMP, "^NEWOPA[0-9].*"); registry.addPattern(ComponentType.OPAMP_MANUFACTURER, "^NEWOPA[0-9].*"); ``` 2. Add to `getSupportedTypes()`: ```java types.add(ComponentType.OPAMP); types.add(ComponentType.OPAMP_MANUFACTURER); ``` ## Similarity Calculators - `MicrocontrollerSimilarityCalculator` - Compares architecture, flash, RAM, peripherals - `OpAmpSimilarityCalculator` - Compares GBW, slew rate, supply voltage - `VoltageRegulatorSimilarityCalculator` - Compares output voltage, current, dropout - `LogicICSimilarityCalculator` - Compares function, family, voltage levels ## Common Packages | Package | Pins | Description | |---------|------|-------------| | DIP | 8-40 | Through-hole | | SOIC | 8-28 | Surface mount | | TSSOP | 8-56 | Thin small outline | | QFP | 32-256 | Quad flat | | LQFP | 32-256 | Low-profile QFP | | QFN | 8-88 | Quad flat no-lead | | BGA | Various | Ball grid array | --- ## Learnings & Quirks <!-- Record component-specific discoveries, edge cases, and quirks here -->
