Product details

75 Ohm at 100 MHz — what that means on the bench

The BLM15BA750SN1D is a single-line ferrite bead from Murata's EMIFIL series, delivering 75 Ohms impedance at 100 MHz. That impedance peak is where common-mode noise from switching regulators or digital clocks lives — the bead turns that energy into heat instead of letting it ride the signal line into sensitive stages.

0402 footprint — fits a tight board

That footprint is standard for dense consumer and IoT PCBs — it sits between two signal traces without crowding the escape routing under a BGA. Surface-mount only — no leaded option exists in this series.

Frequently asked questions

What is the impedance of BLM15BA750SN1D at 100 MHz?

The BLM15BA750SN1D provides 75 Ohms impedance at 100 MHz, making it effective at filtering noise in the frequency range typical of switching power supplies and digital clocks.

What package does BLM15BA750SN1D come in?

It comes in a 0402 (1005 metric) surface-mount package, measuring 1.00 mm x 0.55 mm with a maximum seated height of 0.55 mm. Supplied in tape and reel or cut tape options.
