Its 75 Ω impedance at 100 MHz is the figure that governs noise attenuation at that frequency — the bead presents a resistive loss to common-mode or conducted EMI components near 100 MHz, converting them to heat rather than reflecting them back into the circuit. ## 300 mA and 200 mΩ DCR — the signal-path budget Rated for a maximum continuous current of 300 mA, with a DC resistance of 200 mΩ maximum. The DCR also sets the self-heating: at 300 mA the I²R loss is 18 mW, well within the 0402 body's dissipation capability at 85 °C ambient. The ferrite material's impedance curve shifts with temperature — the 75 Ω figure at 100 MHz is specified at room temperature; expect the peak impedance frequency to drift slightly across the full range, but the bead remains effective as a broadband suppressor.","metaTitle":"Murata BLM15BD750SN1D Ferrite Bead, 75 Ohms @ 100 MHz","metaDescription":"Murata BLM15BD750SN1D EMIFIL® ferrite bead, 0402 package, 75 Ω impedance at 100 MHz, 300 mA current rating, 200 mΩ DCR.
