# BLM15BD102SZ1D

**Murata Electronics** · Ferrite Beads · 0402

BLM15BD102SZ1D 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 electrode of the two-terminal ferrite bead (1000 ohm ±25% at 100 MHz, rated 200 mA at 125°C, 0.90 ohm max DC resistance); the part has no polarity. |
| 2 | 2 | passive | The other electrode of the two-terminal ferrite bead, interchangeable with the first because the equivalent circuit is marked 'no polarity'. |
