BLM21SP700SH1D

Chip Ferrite Bead Overview

The Murata BLM21SP700SH1D is a single-line ferrite chip bead in the EMIFIL BLM21 series, housed in an 0805 (2012 metric) surface-mount package. It provides an impedance of 70 Ohms at 100 MHz with a maximum DC current rating of 6A. The component operates within a temperature range of -55°C to +125°C and meets AEC-Q200 automotive qualification standards.

Chip Ferrite Bead Feature Summary

• High current handling capability suitable for power line applications
• Automotive-grade reliability certified under AEC-Q200 standards
• Compact 0805 footprint designed for space-constrained PCB layouts

Chip Ferrite Bead Applications

• Power supply noise suppression circuits
• Automotive electronic system filtering
• EMI suppression on high-current signal lines

Chip Ferrite Bead Procurement Notes

Verify the specific suffix against official Murata documentation to confirm exact electrical tolerances and packaging configurations. Ensure the selected variant matches the required impedance tolerance and current rating for the target application circuit design.

Chip Ferrite Bead Selection Notes

Select this component when designing circuits requiring significant current capacity alongside EMI filtering. The 6A rating distinguishes it from lower-current variants in the same series, making it appropriate for main power rails rather than low-power signal lines.

Chip Ferrite Bead Part Context

This part belongs to the BLM21 family of ferrite beads manufactured by Murata Electronics. The SP suffix indicates a specific product line optimized for higher current ratings compared to standard signal filtering components within the broader BLM21 series portfolio.
