# MLF3216-2R2K

**Linekey** · Inductors (SMD) · 1206

MLF3216-2R2K from Linekey, in a 1206. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1 | passive | One terminal electrode of the 2.2 µH ±10% inductor (DCR max 0.50 Ω, rated current 50 mA); the part has no directionality so the terminals are interchangeable. |
| 2 | 2 | passive | Other terminal electrode of the 2.2 µH ±10% inductor (DCR max 0.50 Ω, rated current 50 mA); the part has no directionality so the terminals are interchangeable. |

## CAD (KiCad official)

- Symbol: `MLF3216-2R2K`
- Footprint: `Resistor_SMD:R_1206_3216Metric`
- 3D model: 1206 (KiCad packages3D, STEP)
- 3D model files: `mlf3216-2r2k-etched.step` / `mlf3216-2r2k-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `mlf3216-2r2k.step` / `mlf3216-2r2k.glb` are the bare package body.
