BLM03HB191SN1D

Chip Ferrite Bead Overview

The BLM03HB191SN1D is a single-line ferrite chip bead manufactured by Murata Electronics, designed for surface-mount technology in the 0201 (0603 metric) package. It exhibits an impedance of 190 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. The component supports a maximum DC current of 150 mA and features a maximum DC resistance of 2 Ohms. 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 properties
• Compact 0201 footprint suitable for space-constrained designs
• Single-line configuration for individual signal path filtering

Chip Ferrite Bead Applications

• High-speed data line noise suppression
• Clock circuit interference reduction
• Power supply line filtering in portable devices

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 application circuit. Cross-reference the manufacturer part number with authorized distributor databases to confirm authenticity and availability status before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when a compact ferrite bead is required for high-frequency attenuation on low-current signal lines. The 0201 size limits current handling to 150 mA, making it unsuitable for power rails requiring higher capacity. Verify that the 190 Ohm impedance at 100 MHz aligns with the noise spectrum of the specific circuit being filtered.

Chip Ferrite Bead Part Context

This component belongs to the BLM03 series of ferrite beads from Murata Electronics. The series offers various impedance values and current ratings within the 0201 package format. It is engineered for use in consumer electronics and communication equipment where small form factors and effective EMI suppression are critical design requirements.

Chip Ferrite Bead Replacement Considerations

Consult Murata's official substitution guide or equivalent manufacturer datasheets for compatible parts with matching 0201 dimensions, 190 Ohm impedance, and 150 mA current ratings. Ensure any substitute maintains the same thermal characteristics and mounting compatibility.
