BLM03HD182FZ1D

Chip Ferrite Bead Overview

The Murata BLM03HD182FZ1D is a single-line ferrite bead chip designed for high-frequency noise suppression. It features an impedance of 1.8 kOhms at 100 MHz and a maximum DC resistance of 3.8 Ohms. The component supports a rated current of 100 mA and operates within a temperature range of -55°C to +125°C. Housed in a compact 0201 (0603 metric) surface-mount package with dimensions of 0.60 mm x 0.30 mm x 0.33 mm, it meets AEC-Q200 automotive qualification standards.

Chip Ferrite Bead Feature Summary

• Horizontal winding inner coil structure enables low storage capacitance for effective noise suppression up to 1 GHz.
• Automotive-grade reliability certified under the AEC-Q200 standard for harsh environment durability.
• Compact 0201 footprint allows for dense circuit board layouts while maintaining signal integrity.

Chip Ferrite Bead Applications

• High-speed data line filtering in automotive infotainment systems
• Noise suppression for USB and HDMI interfaces in consumer electronics
• Signal conditioning for processor power distribution networks

Chip Ferrite Bead Procurement Notes

Verify the suffix Z1D confirms the specific tape-and-reel packaging configuration required for automated assembly. Confirm RoHS3 compliance status matches current regulatory requirements for the target market. Ensure the ordering quantity aligns with the manufacturer's standard reel size to avoid cut-tape premiums or minimum order constraints during procurement.

Chip Ferrite Bead Selection Notes

Select this component when space-constrained designs require high impedance in a 0201 package. The 100 mA current rating suits low-power signal lines rather than power rails. Verify that the 3.8 Ohm DC resistance does not introduce unacceptable voltage drop in the specific circuit path. Consider the AEC-Q200 certification if the application demands automotive-grade reliability standards.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM series of multi-layer ferrite beads. The BLM03H sub-series specifically targets automotive applications requiring robust performance. It serves as a passive EMI filter component, distinct from active filters or inductors, focusing on broadband noise absorption through magnetic loss mechanisms in the ferrite material.

Chip Ferrite Bead Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other BLM03HD variants only if impedance and current ratings match exactly. Verify pin compatibility and thermal characteristics before substituting with components from different manufacturers.
