BLM03BX102SN1D

Chip Ferrite Bead Overview

The Murata BLM03BX102SN1D is a single-line chip ferrite bead in an 0201 (0603 metric) surface-mount package. It provides an impedance of 1 kOhms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 170 mA and has a maximum DC resistance of 1.7 Ohms. It operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Designed for power supply circuits requiring high rated current suppression
• Suitable for suppressing high-frequency noise in signal lines
• Compact 0201 footprint for dense PCB layouts

Chip Ferrite Bead Applications

• Power supply circuit filtering
• High-frequency noise suppression in signal lines
• EMI suppression in compact electronic devices

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SN1D against official Murata documentation to confirm packaging and tape/reel specifications. Ensure the 0201 package size aligns with the target PCB land pattern. Confirm RoHS compliance status through the manufacturer's latest datasheet or certification documents before finalizing procurement.

Chip Ferrite Bead Selection Notes

Select this component when space constraints require an 0201 footprint while maintaining significant current handling capabilities relative to its size. The 1 kOhm impedance at 100 MHz targets common EMI frequencies. Verify that the 170 mA rating exceeds the peak operating current of the protected line to prevent saturation.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM series of chip ferrite beads, specifically engineered for EMI suppression. The BLM03BX variant indicates a construction optimized for higher current ratings compared to standard signal line beads, making it suitable for mixed-signal environments where both noise control and power integrity are critical.

Chip Ferrite Bead Replacement Considerations

Cross-reference with other Murata BLM03BX variants for identical electrical characteristics but different packaging options. Verify physical dimensions and terminal configurations match the existing design to ensure direct replacement without layout modifications.
