Its 30 Ohm impedance at 100 MHz targets moderate-frequency noise on a power rail or signal line — not the high-impedance suppression of a 1 kOhm bead, but enough to knock down switching harmonics without dropping much DC voltage. ## 1.1 A current rating and 60 mOhm DCR — the DC trade-off Rated for 1.1 A continuous with a maximum DC resistance of 60 mOhm. At full current the resistive loss is about 73 mW — negligible for most rails, but worth checking if the bead sits on a 1.8 V or 1.2 V supply where that drop eats into the voltage margin.","metaTitle":"Murata BLM15AX300SN1D Ferrite Bead, 30 Ohm @ 100 MHz, 1.1 A","metaDescription":"Active Murata BLM15AX300SN1D ferrite bead, 30 Ohm impedance at 100 MHz, 1.1 A current rating, 60 mOhm DCR, 0402 package, -55 to +125 °C.
