It delivers 220 Ohms impedance at 100 MHz with a 600 mA current rating and 180 mOhm max DCR. ## DCR and current — the thermal budget The 180 mOhm max DCR at 600 mA produces I²R losses of about 65 mW — negligible in free air but worth checking if the bead sits in a dense 0402 cluster near a heat source. The 600 mA rating is the continuous DC limit; above that the ferrite saturates and the impedance drops. Surface-mount 0402 footprint with a 0.55 mm max seated height — the low profile fits tight board stacks in automotive ECU enclosures where z-axis clearance is constrained.","metaTitle":"Murata BLM15AX221SZ1D Ferrite Bead, 220 Ohm @ 100 MHz","metaDescription":"Murata BLM15AX221SZ1D ferrite bead, 220 Ohm @ 100 MHz, 600 mA, 180 mOhm DCR, AEC-Q200, 0402.
