**CENKER** · Power Inductors · 0603

CKCW0603-180nH from CENKER, in a 0603. 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 electrode of the 180nH wire-wound inductor (H/J/K tolerance, 1.38 Ω max DCR, 180 mA max Irms, 1300 MHz min SRF); the part is non-polarized. |
| 2 | 2 | passive | Other electrode of the 180nH wire-wound inductor (Ag/Ag-Pd with Ni and Sn plating, 0.1 mm max electrode coplanarity); the part is non-polarized. |
