BLM18BB470SN1D

Chip Ferrite Bead Overview

The Murata BLM18BB470SN1D is a single-line chip ferrite bead in the EMIFIL BLM18BB series, housed in a 0603 (1608 metric) surface-mount package. It provides an impedance of 47 Ohms at 100 MHz with a maximum DC resistance of 250 mOhms and a rated current of 550 mA. The component operates within a temperature range of -55°C to +125°C and measures 1.6 mm in length, 0.8 mm in width, and 0.8 mm in height.

Chip Ferrite Bead Feature Summary

• Designed to function as a resistor at noise frequencies to minimize resonance risks
• Provides effective EMI suppression for high-speed signal lines
• Constructed from ferrite material for efficient noise absorption

Chip Ferrite Bead Applications

• EMI suppression filters
• High-speed signal line filtering

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'SN1D' against official Murata documentation to confirm packaging type and tape dimensions. Ensure the selected variant matches the required 0603 footprint and electrical ratings for the target circuit design before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when a 47 Ohm impedance at 100 MHz is required for noise suppression on single signal lines. The 550 mA current rating suits moderate power applications, while the low DC resistance helps maintain signal integrity in sensitive high-speed digital circuits.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM18BB series of chip ferrite beads. These components are engineered for surface-mount technology and are commonly used in portable electronic devices and industrial equipment where space constraints and effective electromagnetic interference mitigation are critical design factors.

Chip Ferrite Bead Replacement Considerations

Consult official Murata substitution guides for compatible parts within the BLM18 family or equivalent ferrite beads from other manufacturers that match the 0603 footprint, 47 Ohm impedance, and 550 mA current specifications.
