# Capacitor Component Skill Guidance for working with capacitor components in the lib-electronic-components library. ## Supported Manufacturers & Patterns | Manufacturer | Handler | MPN Patterns | Example | |--------------|---------|--------------|---------| | Murata | `MurataHandler` | `GRM...`, `GCM...`, `KCA...` | `GRM188R71H104KA93D` | | Samsung | `SamsungHandler` | `CL10B...`, `CL21B...`, `CL31B...` | `CL10B104KB8NNNC` | | TDK | `TDKHandler` | `CH#...`, `MLF#...` | `C1608X5R1C104K` | | Yageo | `YageoHandler` | `CC####...` | `CC0603KRX7R9BB104` | | KEMET | `KemetHandler` | `C####...` | `C0603C104K5RACTU` | | AVX | `AVXHandler` | `TAJ...`, `TPS...`, `TCJ...` | `TAJB106K016RNJ` | | Nichicon | `NichiconHandler` | `UUD...`, `UPW...`, `UVR...` | `UUD1C101MCL1GS` | | Panasonic | `PanasonicHandler` | `ECQ...`, `EEF...`, `ECA...` | `EEEFC1V100P` | ## ComponentTypes ```java // Base type ComponentType.CAPACITOR // Manufacturer-specific types ComponentType.CAPACITOR_CERAMIC_MURATA ComponentType.CAPACITOR_CERAMIC_TDK ComponentType.CAPACITOR_CERAMIC_SAMSUNG ComponentType.CAPACITOR_CERAMIC_YAGEO ComponentType.CAPACITOR_CERAMIC_KEMET ComponentType.CAPACITOR_CERAMIC_AVX ComponentType.CAPACITOR_TANTALUM_KEMET ComponentType.CAPACITOR_TANTALUM_AVX ComponentType.CAPACITOR_ELECTROLYTIC_PANASONIC ComponentType.CAPACITOR_ELECTROLYTIC_NICHICON ComponentType.CAPACITOR_FILM_KEMET ComponentType.CAPACITOR_FILM_PANASONIC ComponentType.CAPACITOR_POLYMER_AVX ``` ## MPN Structure ### Murata GRM Series (MLCC) ``` GRM 188 R7 1H 104 K A93 D │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ └── Packaging (D=180mm Reel) │ │ │ │ │ │ └────── Special code │ │ │ │ │ └──────── Tolerance (K=±10%) │ │ │ │ └──────────── Value (104=100nF) │ │ │ └─────────────── Voltage (1H=50V) │ │ └────────────────── Dielectric (R7=X7R) │ └────────────────────── Size (188=0603) └────────────────────────── Series (GRM=General) ``` ### KEMET C Series ``` C 0603 C 104 K 5R AC TU │ │ │ │ │ │ │ │ │ │ │ │ │ │ │ └── Packaging (TU=7" Reel) │ │ │ │ │ │ └───── Termination (AC=Flex) │ │ │ │ │ └──────── Voltage (5R=50V) │ │ │ │ └────────── Tolerance (K=±10%) │ │ │ └────────────── Value (104=100nF) │ │ └──────────────── Dielectric (C=X7R) │ └───────────────────── Size (0603) └─────────────────────── Series ``` ## 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 1. In the manufacturer handler's `initializePatterns()`: ```java registry.addPattern(ComponentType.CAPACITOR, "^NEWCAP[0-9]{4}.*"); registry.addPattern(ComponentType.CAPACITOR_CERAMIC_MANUFACTURER, "^NEWCAP[0-9]{4}.*"); ``` 2. Add to `getSupportedTypes()`: ```java 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 ## Common Package Sizes | Code | Metric | Size (mm) | |------|--------|-----------| | 0402 | 1005 | 1.0 x 0.5 | | 0603 | 1608 | 1.6 x 0.8 | | 0805 | 2012 | 2.0 x 1.25 | | 1206 | 3216 | 3.2 x 1.6 | ## Murata Size Codes | Code | Imperial | |------|----------| | 155 | 0402 | | 188 | 0603 | | 21 | 0805 | | 31 | 1206 | | 32 | 1210 | --- ## Learnings & Quirks <!-- Record component-specific discoveries, edge cases, and quirks here -->
