That impedance peak is where common-mode switching noise from a nearby DC-DC converter or digital bus lives — the bead presents a resistive loss at that frequency, dissipating the noise as heat rather than reflecting it back onto the rail. Rated for 200 mA continuous current with a maximum DC resistance of 600 mOhm. The voltage drop across the bead at full rated current is 120 mV — budget this into the rail tolerance if the bead sits on a low-voltage supply like 1.8 V or 1.2 V. ## 0402 footprint and temperature envelope Operating temperature range spans -55°C to +125°C, covering industrial and automotive ambient conditions. No derating curve is published in the spec record, but the 125°C ceiling is the junction/body limit — the 200 mA current rating should be derated above 85°C per standard ferrite practice. ## Active production — sourcing posture Listed as Active by Murata Electronics.","metaTitle":"Murata BLM15BD471SN1D Ferrite Bead, 470 Ω @ 100 MHz, 200 mA","metaDescription":"Murata BLM15BD471SN1D EMIFIL ferrite bead, 470 Ω impedance at 100 MHz, 200 mA rated current, 600 mΩ DCR max, 0402 package, -55 to +125 °C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["EMI Filters & Ferrite Beads"],"specifications":{"Mfr":"Murata Electronics","Series":"EMIFIL®, BLM15","Package":"Tape & Reel (TR); Cut Tape (CT)","Ratings":"-","Filter Type":"Signal Line","Height (Max)":"0.022\\\" (0.55mm)","Mounting Type":"Surface Mount","Package / Case":"0402 (1005 Metric)","Product Status":"Active","Number of Lines":"1","lifecycle_stage":"unknown","Size / Dimension":"0.039\\\" L x 0.022\\\" W (1.00mm x 0.55mm)","Base Product Number":"BLM15BD","Current Rating (Max)":"200mA","Impedance @ Frequency":"470 Ohms @ 100 MHz","Operating Temperature":"-55°C~125°C","DC Resistance (DCR) (Max)":"600mOhm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1000","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/73c2e560dc04bcd20af9d3bc02fbbc8b.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the impedance and current rating of BLM15BD471SN1D?","answer":"The bead provides 470 Ohms impedance at 100 MHz and is rated for 200 mA maximum continuous current with a DC resistance of 600 mOhm max."},{"question":"What package size is BLM15BD471SN1D?","answer":"It comes in an 0402 (1005 Metric) surface-mount package, measuring 1.00 mm x 0.55 mm with a 0.55 mm seated height."},{"question":"Where can I buy BLM15BD471SN1D and check availability?","answer":"Sourced to order against the BOM through independent distribution."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/murata-electronics/BLM15BD471SN1D","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/murata-electronics/BLM15BD471SN1D when reusing this data.
