Product details

470 Ohms at 100 MHz — suppression band anchor

The BLM15BD471SH1D is a single-line ferrite bead from Murata's EMIFIL BLM15 series, delivering 470 Ohms impedance at 100 MHz. This is the spec that sets the noise attenuation peak — for a clock line or data trace carrying a 100 MHz harmonic, the bead presents a resistive loss of 470 Ohms, converting the common-mode or differential noise into heat rather than reflecting it back into the circuit.

0402 footprint — board-fit constraint

The footprint matches standard 0402 land patterns — no special pad geometry required. Surface-mount reflow profile follows the standard lead-free solder curve for this package size.

Frequently asked questions

What is the impedance rating of BLM15BD471SH1D?

470 Ohms at 100 MHz. This is the nominal impedance at the test frequency — the bead's effective suppression band centers around that point, with impedance rolling off above 1 GHz.

What package does BLM15BD471SH1D come in?

0402 (1005 Metric) surface-mount package, 1.00 mm x 0.50 mm, 0.55 mm max height. Supplied in tape and reel (cut tape available).
