BLM18RK102SN1D from Murata Electronics, 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 terminal electrode of the two-terminal ferrite bead (series element, 1000Ω±25% at 100MHz, rated 200mA, max DC resistance 0.80Ω); the part is non-polarised so the terminals are interchangeable. |
| 2 | 2 | passive | Other terminal electrode of the two-terminal ferrite bead (series element, 1000Ω±25% at 100MHz, rated 200mA, max DC resistance 0.80Ω); the part is non-polarised so the terminals are interchangeable. |
