BLM15AX100SN1D

Chip Ferrite Bead Overview

The BLM15AX100SN1D is a single ferrite chip bead from the Murata BLM15AX series, designed for surface mount applications in the compact 0402 (1005 metric) package. It provides an impedance of 10 ohms at a test frequency of 100 MHz with a tolerance of 50%. The component features a maximum DC resistance of 0.015 Ω and operates within a temperature range of -55 °C to +125 °C. Constructed from ferrite material, it measures 1 mm in length, 0.5 mm in width, and 0.5 mm in height.

Chip Ferrite Bead Feature Summary

• Provides electromagnetic interference suppression through high-frequency impedance characteristics.
• Utilizes a compact 0402 surface mount footprint for space-constrained circuit designs.
• Constructed from ferrite material to absorb noise energy effectively.

Chip Ferrite Bead Applications

• High-speed data line filtering
• Power supply noise suppression
• General purpose EMI suppression in portable devices

Chip Ferrite Bead Procurement Notes

Verify the specific impedance tolerance, as documentation indicates both 25% and 50% variants exist for this part number prefix. Confirm RoHS compliance status directly with the manufacturer or authorized distributor before integration. Ensure the selected variant matches the required current handling capabilities for the target application circuit.

Chip Ferrite Bead Selection Notes

Select this component when low impedance values are required for minimal signal attenuation while maintaining noise suppression. The 0402 package size is suitable for dense PCB layouts. Consider the 50% tolerance if precise impedance matching is not critical, or verify if a tighter tolerance variant is available for stricter performance requirements.

Chip Ferrite Bead Part Context

This component belongs to the Murata BLM15AX series of ferrite beads. The series offers various impedance values in the standard 0402 package. The AX suffix typically denotes specific impedance tolerances and characteristics within the broader BLM15 family, distinguishing it from other sub-series like BLH or BLP.
