BLM21BD102SH1D 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 electrode of the two-terminal ferrite bead, 1000Ω ±25% impedance at 100MHz, rated 250mA with 0.4Ω max DC resistance at 85°C (0.5Ω at 125°C).
2 2 passive Other electrode of the two-terminal ferrite bead, interchangeable with the first; the equivalent circuit is a series inductor and resistor between the two terminals, with resistance dominant at high frequencies.
