AFE201210S2R2MBT from Magnetsyc, in a 0805. 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 | Terminal electrode at one end of the 2.0 mm body, a non-polarized inductor terminal rated for Irms 2.0 A typical (1.7 A max) and Isat 2.7 A typical (2.4 A max), with a recommended pad of 0.50 mm gap by 1.30 mm width. |
| 2 | 2 | passive | Terminal electrode at the opposite end of the body, a non-polarized inductor terminal with 2.2 uH at 1 MHz and Rdc 135 mOhm typical (150 mOhm max) between the two terminals. |
