That impedance peak sits right where conducted EMI from switching regulators and digital clocks radiates — the bead turns that energy into heat instead of letting it ride the trace out to the cable or antenna. ## Current ceiling and DC penalty Rated for 200 mA continuous current — push past that and the ferrite material saturates, dropping the effective impedance. The 650 mOhm max DCR means a 130 mV drop at full rated current, which matters if the rail is tight on margin. ## Temperature range and rework reality The 0402 package (1.00 mm x 0.55 mm) is small enough that the hot-air rework profile is forgiving: the part reaches reflow temperature before the adjacent components do, so you can lift it without disturbing the neighbour. Pin 1 is marked by the orientation dot on the top face — check it under magnification before placing, because at this size the dot is easy to miss.","metaTitle":"Murata BLM15BD601SN1D Ferrite Bead, 600 Ohms @ 100 MHz, 0402","metaDescription":"Murata BLM15BD601SN1D EMIFIL ferrite bead, 600 Ohms @ 100 MHz, 200 mA, 650 mOhm DCR, 0402 SMD.

Below that frequency the impedance drops off — the bead does not suppress lower-frequency ripple or DC line noise."},{"question":"What is the maximum DC resistance and why does it matter?","answer":"The max DCR is 650 mOhm. At the 200 mA current rating, that produces a 130 mV voltage drop across the bead. For low-voltage rails (1.8 V or below), this drop can eat into the operating margin and should be factored into the supply budget."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/murata-electronics/BLM15BD601SN1D","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/murata-electronics/BLM15BD601SN1D when reusing this data.
