BLM03AG241SZ1D

Chip Ferrite Bead Overview

The BLM03AG241SZ1D is a single ferrite bead from the Murata BLM03 series, designed for surface-mount applications in the 0201 (0603 metric) package. It exhibits an impedance of 240 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 200 mA and has a maximum DC resistance of 800 mOhms. It operates within a temperature range of -55°C to +125°C and meets AEC-Q200 automotive qualification standards.

Chip Ferrite Bead Feature Summary

• Provides high-frequency noise suppression through significant impedance characteristics at 100 MHz.
• Automotive-grade reliability confirmed by AEC-Q200 qualification for robust performance.
• Compact 0201 footprint enables integration into space-constrained circuit designs.

Chip Ferrite Bead Applications

• High-speed data line filtering in automotive electronic systems
• Power supply noise attenuation in compact mobile devices
• EMI suppression on signal lines in consumer electronics

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'SZ1D' against official Murata documentation to confirm packaging configuration and tape-and-reel specifications. Ensure the selected variant matches the required impedance tolerance and current rating for the target application. Cross-reference the datasheet for any recent product change notifications or material updates before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when a 240 Ohm impedance at 100 MHz is required for noise control in tight spaces. The 200 mA current rating suits low-power signal lines rather than high-current power rails. Consider the 800 mOhms DC resistance impact on voltage drop. The AEC-Q200 certification makes it suitable for automotive environments requiring extended temperature stability.

Chip Ferrite Bead Part Context

This part belongs to the BLM03 family of power ferrite beads manufactured by Murata Electronics. The series focuses on miniaturization while maintaining effective electromagnetic interference suppression capabilities. The 0201 case size represents a standard industry footprint for dense PCB layouts, allowing designers to balance component count with filtering performance in modern electronic assemblies.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include other Murata BLM03AG241 variants with different suffixes if packaging differs. Equivalent parts from other manufacturers must match the 240 Ohm impedance, 200 mA current handling, and 0201 dimensions to ensure mechanical and electrical compatibility without redesigning the footprint.
