BLM15PD600SZ1D

Chip Ferrite Bead Overview

The Murata BLM15PD600SZ1D is a single ferrite chip bead in the BLM15PD series, housed in a 0402 (1005 metric) SMD package. It provides an impedance of 60 Ohms with a 25% tolerance at a test frequency of 100 MHz. The component supports a maximum DC current of 1.7 A and features a maximum DC resistance of 60 mOhms. It operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification.

Chip Ferrite Bead Feature Summary

• AEC-Q200 qualified for automotive reliability standards
• High current handling capability up to 1.7 A
• Compact 0402 surface-mount footprint

Chip Ferrite Bead Applications

• Power supply circuits
• EMI suppression filters

Chip Ferrite Bead Procurement Notes

Verify that the suffix 'SZ' indicates AEC-Q200 automotive qualification, distinct from the standard 'SN' variant which lacks this rating. Confirm the specific impedance value matches the design requirement, as similar part numbers may differ significantly in resistance or current ratings. Ensure the supplier source aligns with the required quality level for automotive applications.

Chip Ferrite Bead Selection Notes

Select this component when high current capacity is required alongside EMI filtering in space-constrained designs. The 0402 package allows for dense PCB layouts. Compare against non-automotive variants if cost reduction is prioritized over certified reliability, ensuring the lower current rating of alternative parts does not compromise circuit performance.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the BLM15PD series, designed for high-current applications. It differs from the BLM15PX series, which offers higher impedance but lower current ratings. The BLM15PD series specifically targets power line noise suppression where significant DC bias currents are present, distinguishing it from general-purpose signal line beads.

Chip Ferrite Bead Replacement Considerations

BLM15PD600SN1D serves as a functional substitute but lacks AEC-Q200 automotive certification. Verify if the application strictly requires the automotive grade qualification before swapping.
