BLM18KG471SZ1D

Murata Electronics · Ferrite Beads · 0603

BLM18KG471SZ1D from Murata Electronics, in a 0603. 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 470 ohm ±25% (at 100MHz) ferrite bead, 1500 mA rated at 85°C and 1000 mA at 125°C, DC resistance 0.130 ohm max. initial; interchangeable with the other terminal.
2 2 passive Other end-electrode of the series ferrite bead (equivalent circuit is inductor in series with resistor between the two terminals), operating temperature -55°C to +125°C.
