Product details

1 kOhm suppression at 100 MHz in a 0402 footprint

The BLM15BD102SH1D is a single-line ferrite bead from Murata's EMIFIL BLM15 series, presenting 1 kOhms of impedance at 100 MHz. That impedance peak is where common-mode noise from switching regulators, clock lines, and digital buses lives — 100 MHz is the sweet spot for suppressing conducted emissions from 48 MHz to 200 MHz harmonics. The single-line differential-mode topology means one bead per noise source — no shared suppression between lines.

Active production — no design-in gate

Murata lists this part as Active. For a new board spin or a BOM refresh, there is no lifecycle-driven reason to second-source it preemptively.

Frequently asked questions

What impedance does BLM15BD102SH1D provide and at what frequency?

It provides 1 kOhms impedance at 100 MHz. That is the standard reference frequency for ferrite bead impedance ratings — the actual impedance curve peaks near that point and rolls off above 300 MHz.

What package size is BLM15BD102SH1D?

0402 (1005 Metric) — 1.00 mm x 0.55 mm footprint, 0.55 mm max seated height. Surface mount, compatible with standard reflow profiles.
