BLM18KG102SH1D

Murata Electronics · Ferrite Beads · 0603

BLM18KG102SH1D 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 two-terminal chip ferrite bead (1000 ohm ±25% at 100MHz, rated current 1000 mA at 85°C and 800 mA at 125°C, DC resistance 0.200 ohm max.).
2 2 passive Other electrode of the two-terminal chip ferrite bead, connected through the series inductor and resistance element shown in the equivalent circuit (symmetric, non-polarized).
