Product details

1 kOhm at 100 MHz in a 0402 body

The BLM15AG102SN1D is a single-line ferrite bead from Murata's EMIFIL® BLM15 series, delivering 1 kOhm impedance at 100 MHz in a standard 0402 (1005 metric) SMD package. Rated for 300 mA continuous current with a max DC resistance of 650 mOhm — the DCR drop at rated current is under 200 mV, so it won't starve a downstream rail in a power-filtering role.

Footprint and board-fit

Surface-mount package, supplied on tape and reel or cut tape; the single-line design means one bead per supply trace, no shared impedance path between rails.

Frequently asked questions

How can I order BLM15AG102SN1D or check availability?

The BLM15AG102SN1D is an active Murata part.

What is the impedance of BLM15AG102SN1D and at what frequency?

It provides 1 kOhm impedance at 100 MHz, which is the standard reference frequency for ferrite bead suppression in the 100 MHz to 1 GHz noise band.

What is the current rating and DC resistance of BLM15AG102SN1D?

Rated for 300 mA maximum with a DCR of 650 mOhm max — the voltage drop at full current is about 195 mV, so budget that into the supply rail margin.
