BLM21BB750SH1D

Chip Ferrite Bead Overview

The Murata BLM21BB750SH1D is a single-line ferrite bead in the EMIFIL BLM21 series, housed in an 0805 (2012 metric) surface-mount package. It provides an impedance of 75 Ohms at 100 MHz with a maximum DC resistance of 160 mOhms and a rated current of 200 mA. The component operates within a temperature range of -55°C to +125°C and complies with RoHS3 standards.

Chip Ferrite Bead Feature Summary

• Designed to function as a resistor at noise frequencies to minimize resonance risks
• Maintains signal waveform integrity during high-frequency noise suppression
• Single-line configuration for differential mode filtering applications

Chip Ferrite Bead Applications

• High-speed digital circuit noise suppression
• Power line filtering for sensitive ICs
• Signal integrity protection in compact mobile devices

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SH1D against official Murata documentation to confirm impedance tolerance and packaging details. Ensure compatibility with standard 0805 reflow profiles and check for AEC-Q200 automotive qualification if required by the target application environment.

Chip Ferrite Bead Selection Notes

Select this component when a low-impedance path is needed for power lines while attenuating high-frequency noise around 100 MHz. The 200 mA rating suits moderate current applications, and the small footprint supports dense PCB layouts requiring efficient EMI control without significant voltage drop.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM21 family of chip ferrite beads, engineered for broadband noise suppression. The series utilizes specialized materials to provide stable impedance characteristics across wide frequency ranges, making it suitable for modern electronics where space constraints and signal purity are critical design factors.

Chip Ferrite Bead Replacement Considerations

Consult Murata's official substitution guide for equivalent parts with matching impedance curves and current ratings. Verify that any alternative maintains the same 0805 footprint and thermal performance specifications to ensure mechanical and electrical compatibility.
