Murata Electronics · Ferrite Beads · 0402
BLM15AX121SN1D11 from Murata Electronics, 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 | Terminal of the chip ferrite bead, 120 ohm ±25% at 100 MHz, rated current 700 mA at 85°C and 600 mA at 125°C. Electrodes are interchangeable, with no polarity. |
| 2 | 2 | passive | Second terminal of the chip ferrite bead, in series with terminal 1 (equivalent circuit is an inductor in series with a resistor), DC resistance 0.13 ohm max at 85°C and 0.18 ohm max at 125°C. |
