**FH Guangdong Fenghua Advanced Tech** · Power Inductors · 0805

CMH201209B2R2MT from FH Guangdong Fenghua Advanced Tech, 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 (Ni/Sn plated Ag) at one end of the 2.2µH ±20% inductor, with RDC 0.20Ω ±25% and rated current 950mA max, SRF 50MHz min. |
| 2 | 2 | passive | Terminal electrode (Ni/Sn plated Ag) at the opposite end of the 2.2µH ±20% inductor; the part is non-polarized and the two terminals are interchangeable. |
