BLM15AX601SN1D

Chip Ferrite Bead Overview

The Murata BLM15AX601SN1D is a single-line ferrite chip bead in the EMIFIL BLM15 series. It features a 0402 (1005 metric) surface-mount package with dimensions of 1.0 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 600 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 500 mA and has a maximum DC resistance of 340 mOhms. The operating temperature range spans from -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides high impedance noise suppression for digital signal lines within compact surface-mount footprints.
• Engineered for stable performance across wide industrial temperature ranges without saturation.
• Designed for automated pick-and-place assembly processes compatible with standard SMT equipment.

Chip Ferrite Bead Applications

• Noise filtering on high-speed data interfaces such as USB and HDMI.
• Suppression of electromagnetic interference on clock signal lines in mobile devices.
• Power line filtering for low-current digital logic circuits in consumer electronics.

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SN1D against official Murata documentation to confirm packaging configuration and tape/reel specifications. Ensure that the requested quantity aligns with manufacturer minimum order requirements for the selected packaging type. Cross-reference the date code and lot number upon receipt to maintain supply chain traceability and quality control standards.

Chip Ferrite Bead Selection Notes

Select this component when circuit design requires 600 Ohms impedance at 100 MHz within a 0402 footprint. Evaluate the 500 mA current rating to ensure it exceeds the peak operational current of the target signal line. Consider the 340 mOhms DC resistance impact on voltage drop for sensitive power rails before finalizing the schematic integration.

Chip Ferrite Bead Part Context

This part belongs to the BLM15 series of ferrite beads, which are optimized for suppressing noise in small electronic devices. The series utilizes Murata's proprietary manufacturing technology to achieve high impedance characteristics in miniature packages. The BLM15AX variant specifically addresses the need for reliable EMI suppression in space-constrained applications like smartphones and tablets.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include other Murata BLM15 series parts with identical impedance and current ratings but different suffixes indicating varied packaging or material compositions. Verify mechanical compatibility and electrical equivalence before swapping components in existing designs.
