Murata Electronics · Ferrite Beads · 0805

BLM21BD102SN1D from Murata Electronics, in a 0805. 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 of two electrodes of the single-circuit chip ferrite bead (1000ohm ±25% at 100MHz/20°C, 200mA rated current, 0.40ohm max. DC resistance); the bead is not polarized.
2 2 passive Other electrode of the single-circuit chip ferrite bead (1000ohm ±25% at 100MHz/20°C, 200mA rated current, 0.40ohm max. DC resistance); the bead is not polarized.

CAD (KiCad official)

  • Symbol: BLM21BD102SN1D
  • Footprint: Inductor_SMD:L_0805_2012Metric
  • 3D model: 0805 (KiCad packages3D, STEP)
  • 3D model files: blm21bd102sn1d-etched.step / blm21bd102sn1d-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); blm21bd102sn1d.step / blm21bd102sn1d.glb are the bare package body.
