**Chilisin Elec** · Inductors (SMD) · 0201

CHQ0603T-3N6C-HU from Chilisin Elec, in a 0201. 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 of the 3.6 nH ±0.2 nH inductor (RDC 0.32 Ω max, IDC 400 mA max, SRF 8100 MHz min). |
| 2 | 2 | passive | Second terminal electrode of the 3.6 nH inductor; the datasheet shows a directionality mark on the body but does not assign pin numbers. |
