BLM21SP700SZ1D

Chip Ferrite Bead Overview

The BLM21SP700SZ1D is a single-line ferrite bead from Murata's EMIFIL BLM21 series, designed for power line noise suppression. It features a 0805 (2012 metric) surface-mount package with dimensions of 2.00mm x 1.25mm and a maximum height of 1.05mm. The component provides an impedance of 70 Ohms at 100 MHz and supports a maximum DC current rating of 6A. It operates within a temperature range of -55°C to +125°C and holds AEC-Q200 automotive qualification.

Chip Ferrite Bead Feature Summary

High current handling capability suitable for power line applications
Automotive-grade reliability through AEC-Q200 qualification
Compact 0805 surface-mount footprint for space-constrained designs

Chip Ferrite Bead Applications

Power line noise filtering in automotive electronics
EMI suppression in high-current DC circuits
Signal integrity protection in automotive control modules

Chip Ferrite Bead Procurement Notes

Verify the suffix 'SZ1D' against official Murata documentation to confirm specific tolerance and packaging specifications. Ensure the selected variant matches the required 6A current rating and 70 Ohm impedance profile for the intended power line application. Cross-reference the AEC-Q200 certification status if automotive compliance is mandatory for the project.

Chip Ferrite Bead Selection Notes

Select this component when a 0805 package size is required alongside a 6A current capacity. The 70 Ohm impedance at 100 MHz targets specific frequency ranges for EMI reduction. Confirm that the operating environment stays within the -55°C to +125°C range and that the PCB layout accommodates the 2.00mm x 1.25mm physical dimensions.

Chip Ferrite Bead Part Context

This part belongs to the Murata EMIFIL BLM21SP series, which specializes in high-current ferrite beads. The SP designation indicates a specific material composition optimized for power lines, distinguishing it from signal line variants. It is part of a broader family of automotive-qualified passive components designed for robust electromagnetic interference suppression.
