BLM03BB750SN1D

Chip Ferrite Bead Overview

The Murata BLM03BB750SN1D is a single-line chip ferrite bead in the EMIFIL BLM03 series, housed in a compact 0201 (0603 metric) surface-mount package. It provides an impedance of 75 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 200 mA and exhibits a maximum DC resistance of 1 Ohm. It operates within a temperature range of -55°C to +125°C and measures 0.60 mm in length, 0.30 mm in width, and 0.33 mm in height.

Chip Ferrite Bead Feature Summary

• Designed to function as a resistor at noise frequencies to minimize resonance risks
• Maintains signal waveform integrity during EMI suppression operations
• Utilizes high-permeability ferrite material for effective broadband attenuation

Chip Ferrite Bead Applications

• Signal line noise filtering in portable electronic devices
• EMI suppression on high-speed digital data lines
• Power supply input filtering for low-current circuits

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SN1D against official Murata documentation to confirm packaging configuration and tape-and-reel specifications. Ensure the selected variant matches the required impedance tolerance and current rating for the target application circuit. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and compliance status before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when space constraints require a 0201 footprint for EMI suppression. The 75 Ohm impedance value is suitable for general-purpose noise reduction where moderate attenuation is sufficient. Verify that the 200 mA current rating exceeds the maximum operating current of the protected line to prevent saturation or excessive heating during normal operation.

Chip Ferrite Bead Part Context

This component belongs to the Murata BLM03 series of chip ferrite beads, which are engineered for compact PCB layouts. The series offers various impedance values and current ratings within the 0201 case size, allowing designers to balance noise suppression performance with physical space limitations in dense consumer electronics and mobile device applications.

Chip Ferrite Bead Replacement Considerations

Compatible substitutes include other Murata BLM03BB750 variants with identical electrical characteristics but different packaging options such as BLM03BB750SN1B or BLM03BB750SN1J. Verify mechanical dimensions and terminal compatibility before substitution.
