BLM18BB471SN1D

Chip Ferrite Bead Overview

The Murata BLM18BB471SN1D is a surface-mount ferrite bead from the BLM18BB series, designed for EMI suppression in compact circuits. It features a 0603 (1608 metric) package with dimensions of 1.6mm length and 0.8mm width. The component provides an impedance of 470 ohms at 100 MHz with a tolerance of 25%. It supports a maximum DC current of 300 mA and has a maximum DC resistance of 850 milliohms. The device operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides high impedance attenuation for noise suppression in signal lines
• Utilizes a compact 0603 surface-mount footprint for space-constrained designs
• Constructed with ferrite material for effective electromagnetic interference filtering

Chip Ferrite Bead Applications

• EMI suppression filters
• Digital interface noise reduction

Chip Ferrite Bead Procurement Notes

Verify the specific electrical parameters against the official Murata datasheet before integration. Confirm that the 300 mA current rating and 850 mΩ DC resistance meet the target circuit requirements. Ensure the 0603 package size aligns with the PCB layout constraints. Check for RoHS compliance status if required by project specifications.

Chip Ferrite Bead Selection Notes

Select this component when a low-current signal line requires moderate noise attenuation in a small form factor. The 300 mA rating suits low-power digital interfaces rather than power delivery paths. Compare against the BLM18KG series if higher current handling is necessary, or the BLM18BD series if lower current but different impedance characteristics are preferred.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM18BB series of chip ferrite beads. These components are engineered for general-purpose EMI suppression in consumer electronics and industrial equipment. The series offers various impedance values within the standard 0603 package, allowing designers to tailor noise filtering without increasing board space.
