BLM15GA750SZ1D

Chip Ferrite Bead Overview

The Murata BLM15GA750SZ1D is a single-line chip ferrite bead in the BLM15_Z series, housed in an unshielded 0402 (1005 metric) SMD package. It provides 75 Ohms impedance at a test frequency of 100 MHz with a tolerance of ±25%. The component supports a maximum DC current of 200 mA and has a maximum DC resistance of 1.3 Ohms. It operates within a temperature range of -55°C to +125°C and meets AEC-Q200 automotive qualification standards.

Chip Ferrite Bead Feature Summary

• Provides signal line noise suppression through high-impedance characteristics at specific frequencies
• Automotive-grade reliability certified under AEC-Q200 standards for harsh environment operation
• Compact surface-mount design suitable for space-constrained PCB layouts

Chip Ferrite Bead Applications

• Noise filtering on signal lines in automotive electronic systems
• High-frequency interference suppression in compact consumer electronics
• Power integrity management in circuits requiring low DC resistance

Chip Ferrite Bead Procurement Notes

Verify the complete part number including suffixes against official manufacturer documentation to ensure correct impedance and current ratings. Confirm RoHS compliance status and AEC-Q200 certification requirements for your specific application environment before ordering.

Chip Ferrite Bead Selection Notes

Select this component when a 75 Ohm impedance at 100 MHz is required for a single-line signal path. Ensure the circuit current does not exceed 200 mA to prevent saturation. The 0402 footprint must be compatible with your board design constraints and assembly capabilities.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the BLM15_Z series from Murata Electronics, designed for general-purpose noise suppression. The series offers various impedance values in a standardized 0402 package, allowing designers to select appropriate components based on specific frequency and current requirements without changing the physical footprint.

Chip Ferrite Bead Replacement Considerations

Check for other BLM15GA variants with different impedance values if the 75 Ohm specification does not match the target frequency response. Verify that any substitute maintains the same 0402 package dimensions and AEC-Q200 qualification if automotive use is intended.
