BLM15AG102SZ1D

Chip Ferrite Bead Overview

The Murata BLM15AG102SZ1D is a single-chip ferrite bead in the 0402 (1005 metric) surface-mount package. It provides an impedance of 1000 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 300 mA and exhibits a maximum DC resistance of 650 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

• Provides high-impedance noise suppression for high-speed signal lines
• AEC-Q200 qualified for automotive electronic applications
• Compact 0402 footprint suitable for space-constrained designs

Chip Ferrite Bead Applications

• EMI suppression filters for high-speed data interfaces
• Noise filtering in automotive electronic control units
• Signal integrity protection in portable communication devices

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'SZ1D' against official Murata documentation to confirm exact electrical tolerances and packaging specifications. Ensure the selected variant matches the required AEC-Q200 qualification status if used in automotive contexts. Cross-reference datasheets for precise DC resistance values as manufacturing batches may vary slightly.

Chip Ferrite Bead Selection Notes

Select this component when a 1 kOhm impedance is required at 100 MHz for noise attenuation. The 300 mA current rating suits moderate-power signal lines. The 0402 size offers a balance between performance and board real estate. Verify thermal management requirements given the low power dissipation capabilities inherent to small ferrite beads.

Chip Ferrite Bead Part Context

This part belongs to the BLM15 series of chip ferrite beads, designed for EMI suppression. The series utilizes Murata's proprietary monolithic ferrite technology to provide effective broadband noise absorption. The BLM15AG variant specifically targets applications requiring stable impedance characteristics over a wide temperature range.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include other Murata BLM15AG102 variants with compatible suffixes. Equivalent parts from other manufacturers must match the 0402 package, 1000 Ohm impedance at 100 MHz, and 300 mA current rating. Verify lead frame material and termination plating for solderability compatibility.
