Inductance Encoding

Sunlord uses a 3-character inductance code:

R-Notation (Decimal Point)

| Code | Value | Calculation | |------|-------|-------------| | R47 | 0.47uH | 0.47 | | R10 | 0.10uH | 0.10 | | 1R0 | 1.0uH | 1.0 | | 2R2 | 2.2uH | 2.2 | | 4R7 | 4.7uH | 4.7 |

3-Digit Code (Multiplier)

| Code | Value | Calculation | |------|-------|-------------| | 100 | 10uH | 10 x 10^0 | | 101 | 100uH | 10 x 10^1 | | 102 | 1000uH (1mH) | 10 x 10^2 | | 220 | 22uH | 22 x 10^0 | | 221 | 220uH | 22 x 10^1 | | 470 | 47uH | 47 x 10^0 | | 471 | 470uH | 47 x 10^1 |

Decoding Algorithm

// R at start = sub-1uH value
if (code.startsWith("R")) {
    return Double.parseDouble("0." + code.substring(1));  // R47 -> 0.47
}

// R in middle = decimal point
if (code.contains("R")) {
    return Double.parseDouble(code.replace("R", "."));  // 1R0 -> 1.0
}

// 3-digit code: first 2 digits x 10^(3rd digit)
int mantissa = Integer.parseInt(code.substring(0, 2));
int exponent = Integer.parseInt(code.substring(2, 3));
return mantissa * Math.pow(10, exponent);  // 101 -> 10 x 10^1 = 100

Impedance Encoding (Ferrite Beads)

GZ series uses 3-digit impedance code (at 100MHz):

| Code | Impedance | Calculation | |------|-----------|-------------| | 601 | 600 ohm | 60 x 10^1 | | 121 | 120 ohm | 12 x 10^1 | | 102 | 1000 ohm | 10 x 10^2 | | 220 | 22 ohm | 22 x 10^0 |

int mantissa = Integer.parseInt(code.substring(0, 2));
int exponent = Integer.parseInt(code.substring(2, 3));
return mantissa * Math.pow(10, exponent);  // 601 -> 60 x 10^1 = 600

Package Size Codes

Metric to Imperial Conversion

| Metric (mm) | Imperial | Notes | |-------------|----------|-------| | 1005 | 0402 | 1.0 x 0.5mm | | 1608 | 0603 | 1.6 x 0.8mm | | 2012 | 0805 | 2.0 x 1.2mm | | 3216 | 1206 | 3.2 x 1.6mm | | 3225 | 1210 | 3.2 x 2.5mm | | 4516 | 1806 | 4.5 x 1.6mm | | 4520 | 1808 | 4.5 x 2.0mm | | 4532 | 1812 | 4.5 x 3.2mm | | 5025 | 2010 | 5.0 x 2.5mm | | 6332 | 2512 | 6.3 x 3.2mm |

Power Inductor Sizes (Stay Metric)

Handler Implementation Notes

Series Extraction

// Returns series + size as the full series identifier
// Example: SDCL1005C1R0MTDF -> "SDCL1005"

if (mpn.startsWith("SDCL")) {
    return "SDCL" + mpn.substring(4, 8);  // SDCL + 4-digit size
}
if (mpn.startsWith("SWPA")) {
    return "SWPA" + mpn.substring(4, 8);
}
if (mpn.startsWith("SDFL")) {
    return "SDFL" + mpn.substring(4, 8);
}
if (mpn.startsWith("GZ")) {
    return "GZ" + mpn.substring(2, 6);  // GZ only has 2-letter prefix
}

Package Code Extraction

// Extract 4-digit size code and convert to imperial
String sizeCode = extractSizeCode(mpn);  // e.g., "1005"
String imperial = SIZE_TO_IMPERIAL_MAP.get(sizeCode);  // e.g., "0402"
return imperial != null ? imperial : sizeCode;

Value Extraction

// For inductors (SDCL, SWPA, SDFL) - extract inductance
public String extractInductanceValue(String mpn) {
    // Match pattern and extract value code from group 4
    Matcher m = SDCL_PATTERN.matcher(mpn);
    if (m.matches()) {
        return parseInductanceCode(m.group(4));
    }
    // ... similar for SWPA, SDFL
}

// For ferrite beads (GZ) - extract impedance
public String extractImpedanceValue(String mpn) {
    Matcher m = GZ_PATTERN.matcher(mpn);
    if (m.matches()) {
        return parseImpedanceCode(m.group(4));
    }
}

Component Types

Sunlord products map to:

INDUCTOR - All inductor products
IC - Also registered under IC for pattern matching compatibility

Note: Handler registers both types for each pattern.

Learnings & Edge Cases

GZ series prefix length: GZ has only 2 letters before size code, unlike SDCL/SWPA/SDFL which have 4.
Value position varies: In SDCL/SWPA/SDFL the value follows an optional type code. Pattern matching must be flexible.
Imperial conversion: Standard chip sizes convert to imperial. Power inductor sizes stay metric (4020 stays 4020).
Type code is optional: The single letter between size and value may be empty in some MPNs.
Ferrite beads vs inductors: GZ series stores impedance, not inductance. Different extraction method needed.
Tolerance position: Tolerance (M/K/J) appears immediately after the value code.
