This impedance value determines the attenuation of conducted noise at the switching or clock frequency — a 470 Ohm bead at 100 MHz provides roughly 20 dB of insertion loss into a 50 Ohm system, which is typical for suppressing harmonics from a DC-DC converter or digital bus. Rated for 200 mA continuous current, this bead can handle most low-power signal lines (I2C, SPI, sensor outputs) without saturating the ferrite material. The DC resistance of 1.3 Ohm max means a 200 mA load drops 260 mV — budget this into the rail voltage if the bead sits in a power path, but for signal lines the drop is negligible. AEC-Q200 qualification means this ferrite bead has passed the passive-component stress tests for automotive electronics: thermal shock, moisture resistance, vibration, and solderability. ## 0402 footprint and board integration This is a standard two-terminal chip footprint — no special pad geometry beyond the IPC-7351 recommendation for 0402. The single-line filter topology means one bead per signal trace; no shared ground plane or via stitching required.","metaTitle":"Murata BLM15GG471SZ1D Ferrite Bead, 470 Ohm @ 100 MHz, 0402","metaDescription":"Murata BLM15GG471SZ1D EMIFIL® ferrite bead, 470 Ohm impedance at 100 MHz, 200 mA, 0402 package, AEC-Q200.
