BLM15AX700SZ1D

Chip Ferrite Bead Overview

The Murata BLM15AX700SZ1D is a single-line ferrite chip bead from the EMIFIL BLM15 series, designed for surface-mount applications in the 0402 (1005 metric) package. It provides an impedance of 70 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 780 mA and features a maximum DC resistance of 100 mOhms. It operates within a temperature range of -55°C to +125°C and has a maximum height of 0.55 mm.

Chip Ferrite Bead Feature Summary

• Provides electromagnetic interference suppression through high-impedance characteristics at target frequencies.
• Supports high-current operation suitable for power and signal line filtering applications.
• Utilizes a compact 0402 surface-mount footprint for dense circuit board layouts.

Chip Ferrite Bead Applications

• Power supply noise filtering
• Signal line EMI suppression
• High-frequency circuit protection

Chip Ferrite Bead Procurement Notes

Verify the suffix 'SZ' against official Murata documentation to confirm specific packaging or tape-and-reel specifications, as standard datasheets may list 'SN'. Ensure the selected variant matches the required handling and storage conditions for the specific manufacturing process.

Chip Ferrite Bead Selection Notes

Select this component when a 70 Ohm impedance at 100 MHz is required in a 0402 package. The 780 mA rating distinguishes it from lower-current variants like the BLM02 series. Confirm that the 100 mOhm DCR meets the voltage drop requirements of the target circuit design.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM15AX series, which offers enhanced current handling capabilities compared to standard BLM15 models. The series is engineered for general-purpose noise suppression in portable electronics and industrial equipment requiring robust performance in small form factors.

Chip Ferrite Bead Replacement Considerations

BLM15AX700SN1D shares identical electrical parameters including 70 Ohms impedance and 780 mA current rating. Verify if the packaging suffix difference impacts automated assembly requirements before substitution.
