BLM18HE102SN1D

Murata Electronics · Ferrite Beads · 0603

BLM18HE102SN1D 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 electrode of the single-circuit chip ferrite bead, with 1000 ohm ±25% impedance at 100MHz, 500 ohm min. at 1GHz, and rated current 1000mA at 85°C and 500mA at 125°C.
2 2 passive Other electrode of the chip ferrite bead, with DC resistance 0.35 ohm max. initially and 0.40 ohm max. after testing, interchangeable with the other terminal.

CAD (KiCad official)

  • Symbol: BLM18HE102SN1D
  • Footprint: Inductor_SMD:L_0603_1608Metric
  • 3D model: 0603 (KiCad packages3D, STEP)
  • 3D model files: blm18he102sn1d-etched.step / blm18he102sn1d-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); blm18he102sn1d.step / blm18he102sn1d.glb are the bare package body.
