Inductance Encoding
Cyntec uses standard R-notation:
R-Notation (Decimal Point)

|---|---|---|
| R47 | 0.47uH | R at start = sub-1uH |
| R68 | 0.68uH | R at start |
| 1R0 | 1.0uH | R in middle |

| 4R7 | 4.7uH | R in middle |
| 6R8 | 6.8uH | R in middle |
3-Digit Multiplier Code
| Code | Value | Calculation |
|---|---|---|
| 100 | 10uH | 10 x 10^0 |
| 101 | 100uH | 10 x 10^1 |
| 220 | 22uH | 22 x 10^0 |
| 470 | 47uH | 47 x 10^0 |
| 471 | 470uH | 47 x 10^1 |
Decoding Algorithm
// R at start (R47, R68)
if (code.startsWith("R")) {
double value = Double.parseDouble("0." + code.substring(1));
return formatInductance(value);
}
// R in middle (1R0, 2R2)
if (code.contains("R")) {
String[] parts = code.split("R");
double value = Double.parseDouble(parts[0] + "." + parts[1]);
return formatInductance(value);
}
// 3-digit code
if (code.matches("\\d{3}")) {
int mantissa = Integer.parseInt(code.substring(0, 2));
int exponent = Integer.parseInt(code.substring(2, 3));
double microhenries = mantissa * Math.pow(10, exponent);
return formatInductance(microhenries);
}

Handler Implementation Notes
Series Extraction
// Returns series + size + type as the full identifier
// PCMC063T-1R0MN -> "PCMC063T"
// MCPA0504-1R0MN -> "MCPA0504"
Matcher m = PCMC_PATTERN.matcher(upperMpn);
if (m.matches()) {
String type = m.group(3);
return m.group(1) + m.group(2) + (type != null ? 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
// 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
// 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
Pattern.compile(
"^(PCMC)(\\d{3,4})([A-Z]?)[-]?([0-9R]+)([A-Z]*)$"
);
// Groups: (1)series (2)size (3)type (4)value (5)tolerance+options
VCMD Pattern
Pattern.compile(
"^(VCMD)(\\d{3,4})([A-Z]?)[-]?([0-9R]+)([A-Z]*)$"
);
// Same structure as PCMC
MCPA Pattern
Pattern.compile(
"^(MCPA)(\\d{4})[-]?([0-9R]+)([A-Z]*)$"
);
// No type field, 4-digit size only
CMC Pattern
Pattern.compile(
"^(CMC)(\\d{4})[-]?([0-9]+)([A-Z]*)$"
);
// Numeric-only value (impedance), no R-notation
Component Types
Cyntec products map to:
INDUCTOR- All inductor and choke productsIC- 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 |

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.
