# Pulse Electronics Manufacturer Skill ## Manufacturer Overview Pulse Electronics is a leading manufacturer of electronic components specializing in: - **LAN Transformers** - Ethernet isolation transformers (H series, T series) - **Telecom Transformers** - Line interface transformers (T series) - **Power Inductors** - SMD and through-hole inductors (P series) - **Power Electronics** - Power transformers and inductors (PA, PE series) - **LAN Magnetics** - RJ45 connectors with integrated magnetics (J, JK, JXD series) Pulse Electronics is known for high-quality magnetic components used in networking, telecommunications, and power applications. --- ## MPN Structure Pulse Electronics MPNs follow this general structure: ``` [SERIES][PART_NUMBER][SUFFIX] | | | | | +-- NL=Lead-free, NLT=Tape&Reel, S=Standard, G=Green | +-- 4-digit part number (or dash-separated for J series) +-- H, T, P, PA, PE, JD0, JK, JXD, etc. ``` ### Example Decodings ``` H1012NL | | || | | |+-- NL = Lead-free / RoHS compliant | | +--- (no additional variant) | +------ 1012 = Part number +--------- H = LAN Transformer series PE-53680NL | | || | | |+-- NL = Lead-free | +-------- 53680 = Part number +------------ PE = Power Electronics series JD0-0001NL | | || | | |+-- NL = Lead-free | +------- 0001 = Variant number +----------- JD0 = J series LAN Magnetics (RJ45 with magnetics) P0751SNL | | ||| | | ||+-- NL = Lead-free | | |+--- S = Standard variant | +------- 0751 = Part number +--------- P = Power Inductor series ``` --- ## Product Series ### Transformer Series | Series | Type | Description | Pattern | |--------|------|-------------|---------| | H | LAN Transformer | Ethernet isolation transformers | `^H\d{4}[A-Z]*$` | | T | Telecom Transformer | Line interface transformers | `^T\d{4}[A-Z]*$` | | PA | Power Adapter | Power transformers, automotive | `^PA[-]?\d+[A-Z]*$` | | PE | Power Electronics | High-power transformers | `^PE[-]\d+[A-Z]*$` | ### Inductor Series | Series | Type | Description | Pattern | |--------|------|-------------|---------| | P | Power Inductor | General purpose power inductors | `^P\d{4}[A-Z]*$` | | PA | Automotive Inductor | Automotive-grade inductors | `^PA[-]?\d+[A-Z]*$` | | PE | SMD Inductor | Surface mount inductors | `^PE[-]\d+[A-Z]*$` | ### LAN Magnetics (Connectors) Series | Series | Type | Description | Pattern | |--------|------|-------------|---------| | J (JD0, JD1) | LAN Magnetics | RJ45 with integrated magnetics | `^JD\d[-]\d{4}[A-Z]*$` | | JK | RJ45 Jack | Standard RJ45 connector jacks | `^JK\d?[-]?\d+[A-Z]*$` | | JXD | 10G LAN | High-speed 10 Gigabit connectors | `^JXD\d?[-]?\d+[A-Z]*$` | --- ## Suffix Codes ### Common Suffixes | Suffix | Description | |--------|-------------| | NL | Lead-free / RoHS compliant | | NLT | Lead-free, Tape and Reel packaging | | S | Standard variant | | SNL | Standard variant, Lead-free | | G | Green / RoHS | | GNL | Green, Lead-free | | T | Tape and Reel | | TL | Tape and Reel, Lead-free | ### Suffix Position The suffix always appears at the end of the MPN, after the part number: ``` H1012NL -> suffix = "NL" PE-53680NLT -> suffix = "NLT" P0751SNL -> suffix = "SNL" (S + NL combined) JD0-0001NL -> suffix = "NL" ``` --- ## Package Code Extraction Package codes are derived from the suffix. The handler maps suffixes to package descriptions: | Suffix | Extracted Package | |--------|-------------------| | NL | SMD Lead-Free | | NLT | SMD Lead-Free T&R | | S | Standard | | SNL | Standard Lead-Free | | G | Green/RoHS | | GNL | Green Lead-Free | | T | Tape & Reel | | TL | Tape & Reel Lead-Free | **Implementation Note**: If the suffix is not in the map, the raw suffix is returned. ```java // From PulseElectronicsHandler.extractPackageCode() String suffix = extractSuffix(mpn); if (PACKAGE_CODES.containsKey(suffix)) { return PACKAGE_CODES.get(suffix); } return suffix; // Return raw suffix if not mapped ``` --- ## Series Extraction Series extraction uses pattern matching with specific ordering to handle overlapping prefixes: **Extraction Order (Important)**: 1. JXD series (most specific J variant) 2. JK series 3. J series (JD0, JD1, etc.) 4. PE series (before P - more specific) 5. PA series (before P - more specific) 6. P series 7. H series 8. T series ```java // Example extraction results: "H1012NL" -> series = "H" "T1029NL" -> series = "T" "P0751SNL" -> series = "P" "PA-1234NL" -> series = "PA" "PE-53680NL" -> series = "PE" "JD0-0001NL" -> series = "J" // Note: returns "J", not "JD0" "JK0-1234NL" -> series = "JK" "JXD0-5678NL" -> series = "JXD" ``` --- ## Supported ComponentTypes The handler supports these component types: | ComponentType | Description | |---------------|-------------| | `INDUCTOR` | Power inductors (P, PA, PE series) | | `TRANSFORMER_BOURNS` | LAN/telecom/power transformers (H, T, PA, PE series) | | `CONNECTOR` | LAN magnetics connectors (J, JK, JXD series) | | `IC` | Generic fallback type (registered for all patterns) | **Note**: Uses `TRANSFORMER_BOURNS` as there is no Pulse-specific transformer type. --- ## Pattern Matching Rules ### Series Pattern Details ```java // H series - LAN transformers: H followed by 4 digits "^(H)(\\d{4})([A-Z]*)$" // Matches: H1012, H1102, H1188, H1012NL, H1188NLT // T series - Telecom transformers: T followed by 4 digits "^(T)(\\d{4})([A-Z]*)$" // Matches: T1029, T3012, T1029NL // P series - Power inductors: P followed by 4 digits "^(P)(\\d{4})([A-Z]*)$" // Matches: P0751, P1166, P0751SNL // PA series - Power adapters: PA optionally followed by dash, then digits "^(PA)[-]?(\\d+)([A-Z]*)$" // Matches: PA1234, PA-1234, PA1234NL // PE series - Power electronics: PE followed by dash, then digits "^(PE)[-](\\d+)([A-Z]*)$" // Matches: PE-53680, PE-53680NL (dash required) // J series - RJ45 with magnetics: JDn followed by dash and 4 digits "^(JD\\d)[-](\\d{4})([A-Z]*)$" // Matches: JD0-0001, JD1-0005, JD0-0001NL // JK series - RJ45 jacks: JK optionally followed by digit, dash, and digits "^(JK\\d?)[-]?(\\d+)([A-Z]*)$" // Matches: JK0-1234, JK-1234, JK1234 // JXD series - 10G LAN: JXD optionally followed by digit, dash, and digits "^(JXD\\d?)[-]?(\\d+)([A-Z]*)$" // Matches: JXD0-5678, JXD-1234, JXD1234NL ``` --- ## Helper Methods The handler provides several utility methods: ### Product Type Detection ```java handler.getProductType("H1012NL"); // "LAN Transformer" handler.getProductType("P0751SNL"); // "Power Inductor" handler.getProductType("JD0-0001NL"); // "LAN Magnetics RJ45" handler.getProductType("PE-53680NL"); // "Power Electronics" ``` ### Lead-Free Detection ```java handler.isLeadFree("H1012NL"); // true (contains NL) handler.isLeadFree("P0751G"); // true (contains G) handler.isLeadFree("T1029"); // false ``` ### Tape and Reel Detection ```java handler.isTapeAndReel("H1012NLT"); // true (ends with NLT) handler.isTapeAndReel("P0751T"); // true (ends with T) handler.isTapeAndReel("H1012NL"); // false ``` ### Component Category Detection ```java handler.isTransformer("H1012NL"); // true (H series) handler.isTransformer("T1029NL"); // true (T series) handler.isTransformer("PE-53680"); // true (PE series) handler.isInductor("P0751SNL"); // true (P series) handler.isInductor("PA-1234"); // true (PA series) handler.isLanMagnetics("JD0-0001"); // true (J series) handler.isLanMagnetics("JXD0-1234"); // true (JXD series) ``` --- ## Official Replacement Logic The `isOfficialReplacement()` method considers two parts as official replacements if: 1. Both are from the same series (e.g., both H series) 2. Both have the same base part number (without suffix) 3. Only the suffix differs (e.g., NL vs NLT) ```java // These are considered official replacements: handler.isOfficialReplacement("H1012NL", "H1012NLT"); // true (same base, different suffix) handler.isOfficialReplacement("P0751S", "P0751SNL"); // true (same base, different suffix) // These are NOT official replacements: handler.isOfficialReplacement("H1012NL", "H1013NL"); // false (different part numbers) handler.isOfficialReplacement("H1012NL", "T1012NL"); // false (different series) ``` --- ## Example MPNs ### LAN Transformers (H Series) | MPN | Series | Part# | Suffix | Description | |-----|--------|-------|--------|-------------| | H1012NL | H | 1012 | NL | 10/100Base-T LAN transformer, lead-free | | H1102NL | H | 1102 | NL | Gigabit LAN transformer, lead-free |
