BLM15HD182SN1D

Chip Ferrite Bead Overview

The Murata BLM15HD182SN1D is a single-line chip ferrite bead in the EMIFIL BLM15HD series, designed for EMI suppression. It features an impedance of 1800 Ohms at 100 MHz and 2700 Ohms at 1 GHz. The component supports a maximum DC current of 200 mA with a maximum DC resistance of 2.2 Ohms. Housed in a compact 0402 (1005 metric) surface-mount package measuring 1.0 mm x 0.5 mm x 0.5 mm, it operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Utilizes a compact 0402 footprint for dense circuit board layouts

Chip Ferrite Bead Applications

• High-speed signal line filtering
• EMI suppression filters
• Digital electronics noise mitigation
• Mobile electronics interference reduction

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SN1D against official Murata documentation to confirm exact packaging and tape-and-reel specifications. Ensure the procurement channel sources directly from authorized distributors or Murata to guarantee authenticity. Cross-reference the RoHS compliance status with the latest regulatory updates before finalizing orders.

Chip Ferrite Bead Selection Notes

Select this component when high impedance at GHz frequencies is required within a strict 0402 spatial constraint. The 200 mA current rating suits low-power signal lines rather than power distribution paths. Consider the -55°C to +125°C operating range for applications exposed to thermal stress. Verify that the 2.2 Ohm DC resistance does not introduce unacceptable voltage drops in the target circuit.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM15HD series, which specializes in high-performance EMI suppression for digital and mobile devices. The series utilizes advanced ferrite materials to achieve superior noise absorption characteristics compared to standard beads. It serves as a critical passive component for maintaining signal integrity in high-frequency data transmission lines.

Chip Ferrite Bead Replacement Considerations

Consult the official Murata BLM15HD datasheet for direct cross-references. Substitution requires matching the 0402 package dimensions, 1800 Ohm impedance at 100 MHz, and 200 mA current handling capabilities. Verify thermal performance and material compatibility before integrating alternative ferrite beads.
