0402 ferrite bead, 22 Ohms at 100 MHz
The BLM15BB220SH1D is a single-line ferrite bead from Murata's EMIFIL® BLM15 series, offering 22 Ohms impedance at 100 MHz in the compact 0402 (1005 Metric) package. It is a differential-mode filter, meaning it suppresses common-mode noise on a single signal or power line — no ground plane needed for the bead itself.
Board-fit and rework
Surface-mount 0402 footprint, 1.00 mm x 0.50 mm body, 0.55 mm max height. No polarity, no orientation — just drop it in the pad pattern and reflow. For a field repair or rework, standard tweezers and a soldering iron with a fine tip handle it; no hot-air station required unless the board is densely populated.
