**Murata Electronics** · Ferrite Beads · 0201

BLM03AG100SN1D from Murata Electronics, 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 | One terminal of the single-circuit chip ferrite bead (0.15±0.05 mm electrode), rated 500mA at 85°C and 125°C with 0.1Ω max DC resistance, no ground connection needed. |
| 2 | 2 | passive | Second terminal of the single-circuit chip ferrite bead, 10Ω impedance at 100MHz, interchangeable with the other terminal as the part is a non-polarized series element. |
