BLM21BB750SZ1D

Chip Ferrite Bead Overview

BLM21BB750SZ1D is a single-line ferrite bead from the Murata EMIFIL BLM21BB series, designed for surface-mount assembly in the 0805 (2012 metric) package. It provides an impedance of 75 Ohms at 100 MHz with a maximum DC resistance of 160 milliohms and a rated current of 700 mA. The component operates within a temperature range of -55°C to +125°C and has a maximum height of 0.85 mm.

Chip Ferrite Bead Feature Summary

• Provides high-frequency noise suppression through significant impedance characteristics at 100 MHz
• Supports continuous signal line currents up to 700 mA with low DC resistance
• Engineered for reliable operation across extended industrial temperature ranges

Chip Ferrite Bead Applications

• High-speed digital signal line filtering
• Power supply noise attenuation in compact circuits
• EMI suppression in portable electronic devices

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'SZ' against official Murata documentation to confirm material composition and termination specifications. Ensure the selected variant matches the required thermal and electrical ratings for the target application environment before finalizing procurement.

Chip Ferrite Bead Selection Notes

Select this component when a 0805 footprint is required for single-line noise suppression. Compare the 700 mA current rating and 75 Ohm impedance against circuit requirements. Consider the BLM21BB750SN1D if a lower profile or different termination style is preferred for the same electrical performance.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM21BB series of chip ferrite beads. The series offers various impedance values and current ratings in standard SMD packages. The BLM21BB750SZ1D specifically targets applications needing moderate noise filtering with robust current handling capabilities in a compact form factor.

Chip Ferrite Bead Replacement Considerations

The BLM21BB750SN1D is a verified alternative within the same series offering identical electrical parameters. Verify physical dimensions and terminal compatibility before substitution.
