BLM18BA750SH1D

Chip Ferrite Bead Overview

The Murata BLM18BA750SH1D is a single-line differential mode ferrite bead in the BLM18_Z series. It features a 0603 (1608 metric) surface mount package with dimensions of 1.6 mm length, 0.8 mm width, and 0.95 mm height. The component provides an impedance of 75 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 300 mA and has a maximum DC resistance of 700 mOhms. Operating temperatures range from -55°C to +125°C. It is AEC-Q200 qualified and RoHS3 compliant.

Chip Ferrite Bead Feature Summary

• Provides high-frequency noise suppression through differential mode filtering characteristics.
• Designed for compact surface-mount applications using standard 0603 footprints.
• Qualified for automotive reliability standards under AEC-Q200 specifications.

Chip Ferrite Bead Applications

• Automotive electronic circuit noise suppression
• High-speed signal line filtering
• Power supply output decoupling

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SH1D 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. Cross-reference the AEC-Q200 qualification status if automotive compliance is mandatory. Confirm RoHS3 compliance requirements prior to final procurement decisions.

Chip Ferrite Bead Selection Notes

Select this component when a 75 Ohm impedance at 100 MHz is required within a 0603 footprint. The 300 mA current rating suits moderate power lines. Consider the 700 mOhms DC resistance impact on voltage drop. The wide temperature range supports harsh environments. Verify that the single-line configuration meets the circuit topology needs without requiring shielded alternatives.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM18 series of chip ferrite beads. The series offers various impedance values and current ratings in standardized SMD packages. The BLM18BA designation indicates the specific impedance code and series variant within the broader EMIFIL product line designed for EMI suppression in digital and analog circuits.

Chip Ferrite Bead Replacement Considerations

BLM18BB750SZ1D shares similar impedance and package dimensions but may differ in current handling or series specifications. BLM18BA470SH1D offers lower impedance (47 Ohms). Verify electrical parameters and physical compatibility before substitution.
