BLM41PG750SZ1L

Chip Ferrite Bead Overview

The Murata BLM41PG750SZ1L is a single ferrite chip bead in an 1806 (4516 metric) surface-mount package. It provides 75 Ohms impedance at a test frequency of 100 MHz with a 25% tolerance. The component supports a maximum DC current of 3.5 A and has a maximum DC resistance of 15 mOhms. It operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification for automotive reliability.

Chip Ferrite Bead Feature Summary

• AEC-Q200 qualified for automotive electronic applications
• High current handling capability up to 3.5 Amperes
• Low DC resistance design for minimal power loss
• Unshielded single-type ferrite construction

Chip Ferrite Bead Applications

• Automotive power line filtering
• DC-DC converter output noise suppression
• High-current signal line EMI attenuation

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'SZ1L' against official Murata documentation to confirm the 15 mOhm DC resistance specification, as variations exist within the series. Confirm AEC-Q200 certification status directly from the manufacturer datasheet before finalizing procurement for automotive-grade requirements.

Chip Ferrite Bead Selection Notes

Select this component when high current capacity is required alongside moderate impedance filtering. The 1806 footprint offers a balance between current handling and board space. Ensure the application voltage and thermal environment remain within the specified -55°C to +125°C operational limits for reliable performance.

Chip Ferrite Bead Part Context

This part belongs to the BLM41 series of ferrite beads designed for suppressing electromagnetic interference in high-current circuits. The series utilizes Murata's proprietary ferrite material to provide effective noise absorption while maintaining low insertion loss in the passband.

Chip Ferrite Bead Replacement Considerations

Cross-reference with BLM41PG750SN1L for similar impedance but verify if the higher DC resistance meets system efficiency requirements.
