## Inductor Types
| Type | Description | Applications |
|------|-------------|--------------|
| Chip | Multilayer ceramic/ferrite | RF, filtering |
| Power | Shielded/unshielded wound | DC-DC, power |
| Common Mode Choke | Coupled inductors | EMI filtering |

## Related ComponentTypes for EMI
```java
ComponentType.FERRITE_BEAD_TDK
ComponentType.FERRITE_BEAD_YAGEO
ComponentType.EMI_FILTER_MURATA
ComponentType.EMI_FILTER_TDK
ComponentType.COMMON_MODE_CHOKE_MURATA
ComponentType.COMMON_MODE_CHOKE_TDK
```
## Adding New Inductor Patterns
1. In the manufacturer handler's `initializePatterns()`:
```java
registry.addPattern(ComponentType.INDUCTOR, "^NEWIND[0-9]{4}.*");
registry.addPattern(ComponentType.INDUCTOR_CHIP_MANUFACTURER, "^NEWIND[0-9]{4}.*");
```
2. Add to `getSupportedTypes()`:
```java
types.add(ComponentType.INDUCTOR);
types.add(ComponentType.INDUCTOR_CHIP_MANUFACTURER);
```
## Value Notation
| Notation | Value |
|----------|-------|
| 2N2 | 2.2 nH |
| 10N | 10 nH |
| R10 | 0.10 µH |
| 100 | 10 µH (10 × 10^0) |
| 101 | 100 µH (10 × 10^1) |
| 102 | 1000 µH (10 × 10^2) |
## Murata Size Codes
