This impedance peak targets conducted EMI in the 30 MHz to 300 MHz range — the typical switching noise band for DC-DC converters, clock lines, and digital I/O. At 780 mA continuous current rating, the bead maintains its impedance without saturating the ferrite material; above this current the effective impedance drops as the core approaches magnetic saturation. The 0402 footprint (1.00 mm x 0.55 mm body, 0.55 mm max height) fits into dense PCB layouts where board space is at a premium, such as mobile devices, IoT modules, and compact power supplies. The ceramic construction and nickel barrier termination handle thermal cycling without parametric drift — the impedance curve shifts less than 10% across the temperature range per Murata's typical characteristic.","metaTitle":"BLM15AX700SN1D Ferrite Bead, 70 Ohms @ 100 MHz, 780 mA, 0402","metaDescription":"Murata BLM15AX700SN1D EMIFIL ferrite bead, 70 Ohms impedance at 100 MHz, 780 mA current rating, 100 mOhm DCR, 0402 package, -55°C 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":"-","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":"BLM15AX","Current Rating (Max)":"780mA","Impedance @ Frequency":"70 Ohms @ 100 MHz","Operating Temperature":"-55°C ~ 125°C","DC Resistance (DCR) (Max)":"100mOhm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/73c2e560dc04bcd20af9d3bc02fbbc8b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BLM15AX700SN1D/alternatives.json"},"ai":{"faq":[{"question":"What is the impedance of BLM15AX700SN1D and at what frequency?","answer":"70 Ohms at 100 MHz. This is the rated impedance at the specified test frequency — the bead's impedance curve peaks near 100 MHz and rolls off above 1 GHz. For lower-frequency noise (below 10 MHz), a higher impedance value or a different ferrite material grade would be needed."},{"question":"What is the current rating and DC resistance of this ferrite bead?","answer":"Rated 780 mA continuous with a maximum DC resistance of 100 mOhm. The current rating is the DC bias limit before the ferrite material begins to saturate; operating above this current reduces the effective impedance. The DCR determines the resistive voltage drop and self-heating in the power path."},{"question":"What package size is BLM15AX700SN1D?","answer":"0402 (1005 metric) surface mount, measuring 1.00 mm x 0.55 mm with a maximum seated height of 0.55 mm.
