BLM15AX700SN1D

Chip Ferrite Bead Overview

The Murata BLM15AX700SN1D is a single-line ferrite chip bead from the EMIFIL BLM15 series, designed for surface-mount technology in the 0402 (1005 metric) package. It provides an impedance of 70 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 780 mA and features a maximum DC resistance of 100 mOhms. It operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides high-frequency noise suppression through ferrite material characteristics
• Supports automated surface-mount assembly processes
• Maintains low DC resistance to minimize signal loss in power lines

Chip Ferrite Bead Applications

• Noise filtering in portable electronic devices
• Signal integrity management in mobile communication modules
• Power line filtering in compact consumer electronics

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SN1D against official Murata documentation to confirm packaging and tape-and-reel specifications. Ensure the selected variant matches the required impedance tolerance and current rating for the target circuit design before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when space constraints require a 0402 footprint with moderate current handling capabilities. The 70 Ohm impedance value is suitable for suppressing specific noise frequencies around 100 MHz. Verify that the 780 mA current rating exceeds the peak operational current of the protected circuit to prevent saturation.

Chip Ferrite Bead Part Context

This part belongs to the Murata EMIFIL BLM15 series, which offers various impedance values and current ratings in standard 0402 packages. The AX suffix typically denotes specific material properties optimized for general-purpose noise suppression applications within the consumer electronics sector.

Chip Ferrite Bead Replacement Considerations

Direct substitutes must match the 0402 package, 70 Ohm impedance at 100 MHz, and similar current ratings. Consult Murata's official cross-reference tools or distributor databases for verified equivalent part numbers from the same manufacturer.
