# BLM15AX601SN1D

**Murata Electronics** · Ferrite Beads · 0402

BLM15AX601SN1D 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 | One end electrode of the single-circuit chip ferrite bead (600 ohm ±25% at 100MHz, rated current 500mA, DC resistance 0.34 ohm max. initial). |
| 2 | 2 | passive | Other end electrode of the single-circuit chip ferrite bead, interchangeable with the first terminal (equivalent circuit is an inductor in series with a resistor). |
