# BLM15BD102SN1D

**Murata Electronics** · Ferrite Beads · 0402

BLM15BD102SN1D 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 electrode 1 of the two-terminal ferrite bead (1000Ω ±25% at 100MHz, 200mA rated, 0.90Ω max DC resistance); the part is non-polarized so the terminals are interchangeable. |
| 2 | 2 | passive | Terminal electrode 2 of the two-terminal ferrite bead (1000Ω ±25% at 100MHz, 200mA rated, 0.90Ω max DC resistance); the part is non-polarized so the terminals are interchangeable. |
