# CS0402-7N5J-S

**Chilisin Elec** · Inductors (SMD) · 0402

CS0402-7N5J-S from Chilisin Elec, in a 0402. 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 | First terminal of the 7.5 nH wire-wound inductor (CS0402-7N5J-S: 7.5 nH, ±5%, Q min 22 at 250 MHz, RDC 0.10 Ω max, Irms 680 mA max, SRF 4.80 GHz min); the part is non-polar so the terminals are interchangeable. |
| 2 | 2 | passive | Second terminal of the 7.5 nH wire-wound inductor (operating temperature -40 °C to 125 °C including self-temperature rise); the part is non-polar so the terminals are interchangeable. |
