BLM03BC330SN1D

Chip Ferrite Bead Overview

The Murata BLM03BC330SN1D is a single-line ferrite chip bead in the EMIFIL BLM03 series. It features a 0201 (0603 metric) surface-mount package with dimensions of 0.60mm length, 0.30mm width, and 0.33mm height. The component provides an impedance of 33 Ohms at 100 MHz with a tolerance of 25%. It supports a maximum DC current of 150mA and has a maximum DC resistance of 850 milliohms. The operating temperature range spans from -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides signal line noise filtering through high-impedance characteristics at target frequencies
• Utilizes compact 0201 surface-mount packaging for dense circuit board integration
• Constructed as a single-line ferrite bead for targeted EMI suppression

Chip Ferrite Bead Applications

• Signal line noise suppression
• General purpose EMI filtering
• Audio line noise filtering

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SN1D against official Murata documentation to confirm tape-and-reel specifications. Ensure the selected variant matches the required impedance tolerance and current rating for the target application. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm RoHS compliance status and availability. Confirm that the 0201 footprint aligns with the PCB design constraints before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when space-constrained designs require a 0201 footprint for noise suppression. The 150mA current rating suits low-power signal lines rather than power rails. Verify that the 33 Ohm impedance at 100 MHz meets the specific frequency requirements of the noise source. Consider the 850 milliohm DC resistance impact on signal integrity if the line carries sensitive analog data.

Chip Ferrite Bead Part Context

This part belongs to the Murata EMIFIL BLM03 series, which focuses on miniaturized ferrite beads for portable electronics. The BLM03BC variant specifically denotes the 0201 case size within this family. These components are designed to replace larger inductors or resistors in high-density consumer devices where board real estate is limited.
