## Inductance Encoding
Cyntec uses standard R-notation:
### R-Notation (Decimal Point)
| Code | Value | Notes |
|------|-------|-------|
| R47 | 0.47uH | R at start = sub-1uH |
| R68 | 0.68uH | R at start |
| 1R0 | 1.0uH | R in middle |
| 2R2 | 2.2uH | 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
```java
// 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);
}
```

| Code | Dimension |
|------|-----------|
| 063 | 6.3mm |

### 4-Digit Size (MCPA, CMC)
| Code | Dimensions |
|------|------------|
| 0504 | 5.0mm x 4.0mm |

## Package Type by Series

## Handler Implementation Notes
### Series Extraction
```java
// 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
```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 |

## 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.
