BLM03AX100SN1D

Chip Ferrite Bead Overview

The Murata BLM03AX100SN1D is a single-line ferrite chip bead in the BLM03_SN series, housed in a compact 0201 (0603 metric) surface-mount package. It provides an impedance of 10 Ohms with a tolerance of ±25% at a test frequency of 100 MHz. The component supports a maximum DC current of 1 A and features a low maximum DC resistance of 50 mOhms. It operates reliably within a temperature range of -55°C to +125°C, with physical dimensions of 0.6 mm in length, 0.3 mm in width, and 0.3 mm in height.

Chip Ferrite Bead Feature Summary

• Provides high-frequency noise suppression through resistive impedance characteristics
• Designed for space-constrained applications via a miniature 0201 footprint
• Capable of handling significant direct current loads without saturation

Chip Ferrite Bead Applications

• High-speed digital signal line filtering
• Power supply output decoupling
• EMI suppression in portable electronic devices

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SN1D against official Murata documentation to confirm packaging configuration and compliance status. Ensure that the selected variant matches the required impedance tolerance and current rating for the target circuit design before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when a low-impedance path is required for power lines or high-current signals while maintaining basic EMI control. The 1A current rating distinguishes it from higher-impedance variants in the same series which typically support lower current limits. Verify thermal performance under continuous load conditions.

Chip Ferrite Bead Part Context

This part belongs to the BLM03_SN family of ferrite beads manufactured by Murata Electronics. These components are engineered for general-purpose noise suppression in compact consumer electronics and industrial equipment. The series offers various impedance values tailored to different frequency attenuation requirements.

Chip Ferrite Bead Replacement Considerations

Consult official Murata substitution guides for verified equivalents. Cross-referencing requires matching impedance, current rating, and package dimensions.
