BLM15BX750SN1D

Chip Ferrite Bead Overview

The BLM15BX750SN1D is a single-type chip ferrite bead from the Murata BLM15_SN series, housed in a 0402 (1005 metric) SMD package measuring 1 mm x 0.5 mm x 0.5 mm. It provides an impedance of 75 Ohms with a 25% tolerance at a test frequency of 100 MHz. The component supports a maximum DC current of 600 mA and features a maximum DC resistance of 150 mOhms. It operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides signal line noise suppression through high-impedance attenuation at target frequencies
• Designed for surface-mount assembly using standard SMD/SMT termination types
• Constructed as a single-type chip ferrite bead for compact circuit integration

Chip Ferrite Bead Applications

• Signal line filtering in electronic circuits
• Noise suppression on data transmission lines
• EMI reduction in portable devices requiring small form factors

Chip Ferrite Bead Procurement Notes

Verify the specific impedance value and DC current rating against the official Murata datasheet before finalizing design specifications. Confirm that the 0402 package dimensions align with the PCB footprint requirements. Ensure the operating temperature range meets the environmental conditions of the intended application. Cross-reference the manufacturer part number to avoid confusion with similar series variants.

Chip Ferrite Bead Selection Notes

Select this component when a low-profile ferrite bead is required for signal integrity management. The 600 mA current rating suits moderate power signal lines without significant saturation risks. The 75 Ohm impedance offers balanced attenuation characteristics for common digital interfaces. Consider the 150 mOhms DC resistance impact on voltage drop if placed in critical power paths.

Chip Ferrite Bead Part Context

This component belongs to the EMIFIL® BLM15 series, which focuses on miniaturized ferrite solutions. The BX suffix typically denotes specific material or performance characteristics within the broader BLM15 family. These beads are engineered for high-volume manufacturing and consistent electrical performance across automotive and industrial electronics sectors.

Chip Ferrite Bead Replacement Considerations

Consult the official Murata alternate sizing guide for verified substitutes. Direct replacements must match the 0402 package, 75 Ohm impedance, and 600 mA current rating. Generic ferrite beads may not provide equivalent high-frequency attenuation profiles.
