Murata Electronics · Ferrite Beads · 0201

BLM03PX220SN1D from Murata Electronics, in a 0201. 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 ferrite bead (series inductor with resistive element at high frequency); 22 ohm ±25% at 100MHz, rated current 1800 mA at 85°C and 1450 mA at 125°C, DC resistance 0.040 ohm max.
2 2 passive Other electrode of the ferrite bead, interchangeable with the first; the equivalent circuit shows a single two-terminal series element, and the part is operated from -55°C to +125°C.
