type : ""); } m = VCMD_PATTERN.matcher(upperMpn); if (m.matches()) { String type = m.group(3); return m.group(1) + m.group(2) + (type != null ? type : ""); } // MCPA and CMC don't have type suffix m = MCPA_PATTERN.matcher(upperMpn); if (m.matches()) { return m.group(1) + m.group(2); } ``` ### Package Code Extraction ```java // Returns the package type description based on series String series = extractSeriesPrefix(mpn); return SERIES_PACKAGE_MAP.get(series); // Returns: "Power Inductor", "Molded Power Inductor", etc. ``` ### Value Extraction ```java // Value code position varies by series // PCMC/VCMD: group(4) after type // MCPA/CMC: group(3) directly after size Matcher m = PCMC_PATTERN.matcher(mpn); if (m.matches()) { String valueCode = m.group(4); return parseInductanceCode(valueCode); } m = MCPA_PATTERN.matcher(mpn); if (m.matches()) { String valueCode = m.group(3); return parseInductanceCode(valueCode); } ``` --- ## Pattern Details ### PCMC Pattern ```java Pattern.compile( "^(PCMC)(\\d{3,4})([A-Z]?)[-]?([0-9R]+)([A-Z]*)$" ); // Groups: (1)series (2)size (3)type (4)value (5)tolerance+options ``` ### VCMD Pattern ```java Pattern.compile( "^(VCMD)(\\d{3,4})([A-Z]?)[-]?([0-9R]+)([A-Z]*)$" ); // Same structure as PCMC ``` ### MCPA Pattern ```java Pattern.compile( "^(MCPA)(\\d{4})[-]?([0-9R]+)([A-Z]*)$" ); // No type field, 4-digit size only ``` ### CMC Pattern ```java Pattern.compile( "^(CMC)(\\d{4})[-]?([0-9]+)([A-Z]*)$" ); // Numeric-only value (impedance), no R-notation ``` --- ## Component Types Cyntec products map to: - `INDUCTOR` - All inductor and choke products - `IC` - Also registered for pattern matching compatibility --- ## CMC Impedance Encoding Common mode chokes use 3-digit impedance code (like ferrite beads): | Code | Impedance | |------|-----------| | 471 | 470 ohm | | 102 | 1000 ohm | | 222 | 2200 ohm | --- ## Common Part Numbers | MPN | Description | |-----|-------------| | PCMC063T-1R0MN | 1.0uH power inductor, 6.3mm | | VCMD063T-2R2MN | 2.2uH molded inductor, 6.3mm | | MCPA0504-1R0MN | 1.0uH automotive inductor | | CMC0503-471M | 470 ohm common mode choke | --- ## Related Files - Handler: `manufacturers/CyntecHandler.java` - Supported types: `INDUCTOR`, `IC` - No manufacturer-specific ComponentType enum entries --- ## Learnings & Edge Cases - **Variable size digit count**: PCMC/VCMD can have 3 OR 4 digit size codes (063 vs 0504). MCPA/CMC always have 4. - **Type field presence**: PCMC/VCMD have optional type letter (T, S). MCPA/CMC don't have this field. - **CMC uses impedance**: Common mode chokes encode impedance, not inductance. No R-notation allowed. - **Series included in package code**: Unlike other handlers, Cyntec returns the package TYPE name (e.g., "Power Inductor") not size. - **Dash is optional**: The dash before value code may be present or absent. - **N suffix = tape and reel**: Standard packaging suffix. <!-- Add new learnings above this line -->
