Rated for 350 mA continuous current, it handles low-power supply rails and signal lines without saturating the ferrite material. ## AEC-Q200 and the 125 °C ceiling Rated AEC-Q200, this bead is qualified for automotive-grade stress — thermal shock, vibration, and solder heat resistance per the AEC-Q200 passive-component standard. The operating range spans -55 °C to 125 °C, covering under-hood and engine-bay ambient where the bead sits on a PCB near the ECU or a power module. ## 0402 footprint, tape-and-reel delivery Housed in the standard 0402 (1005 Metric) package — 1.00 mm x 0.55 mm, seated height 0.55 mm max. Supplied on tape and reel (Cut Tape also available), compatible with high-speed pick-and-place. The single-line topology means it filters one power or signal trace per component; use one per rail or per I/O line.","metaTitle":"Murata BLM15AX102SZ1D Ferrite Bead, 1 kOhm @ 100 MHz, 350 mA","metaDescription":"Murata BLM15AX102SZ1D ferrite bead, 1 kOhm impedance at 100 MHz, 350 mA current rating, 490 mOhm DCR, 0402 package, AEC-Q200.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["EMI Filters & Ferrite Beads"],"specifications":{"Mfr":"Murata Electronics","Series":"BLM","Package":"Tape & Reel (TR) Cut Tape (CT)","Ratings":"AEC-Q200","Filter Type":"Power, 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":"BLM15AX","Current Rating (Max)":"350mA","Impedance @ Frequency":"1 kOhms @ 100 MHz","Operating Temperature":"-55°C ~ 125°C","DC Resistance (DCR) (Max)":"490mOhm"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.1000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/47421877a8ccd614873519959a109225.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BLM15AX102SZ1D/alternatives.json"},"ai":{"faq":[{"question":"What is the impedance of BLM15AX102SZ1D at 100 MHz?","answer":"1 kOhm at 100 MHz.
