LQM21DH330M70L from Murata Electronics, 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 | Terminal 1 | passive | One end of the 33 µH ±20% winding (inductance at 1 MHz), 2.30 Ω typ / 2.99 Ω max DC resistance, rated 80 mA (inductance-change basis) or 200 mA at 150°C ambient (temperature-rise basis). |
| 2 | Terminal 2 | passive | Other end of the 33 µH winding, interchangeable with terminal 1, with self-resonant frequency of 16 MHz min. |
