BLM03PX800SN1D

Chip Ferrite Bead Overview

The Murata BLM03PX800SN1D is a single-line ferrite chip bead designed for power line noise suppression. It features an 0201 (0603 metric) surface-mount package with dimensions of 0.6 mm length, 0.3 mm width, and 0.3 mm height. The component provides an impedance of 80 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 1 A and has a maximum DC resistance of 130 mOhms. The device operates within a temperature range of -55°C to +125°C.

Chip Ferrite Bead Feature Summary

• Provides effective high-frequency noise attenuation on power lines through ferrite material absorption.
• Utilizes a compact 0201 footprint to maximize board space efficiency in dense layouts.
• Engineered for high-current applications with a rated capacity of 1 A.

Chip Ferrite Bead Applications

• Power supply input filtering
• DC-DC converter output stages
• High-speed digital signal line noise suppression

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SN1D against official Murata documentation to confirm the exact impedance value and tolerance specifications. Ensure that the selected packaging format aligns with automated assembly requirements. Cross-reference the manufacturer part number directly with the datasheet to avoid confusion with similar series variants.

Chip Ferrite Bead Selection Notes

Select this component when space constraints require an 0201 package size while maintaining a 1 A current handling capability. The 80 Ohm impedance at 100 MHz makes it suitable for suppressing common switching frequencies found in modern power electronics. Verify thermal performance under continuous load conditions to ensure the DC resistance does not cause excessive voltage drop.

Chip Ferrite Bead Part Context

This component belongs to the Murata EMIFIL BLM03 series, which focuses on miniaturized noise suppression solutions. The BLM03 series is widely used in portable electronics and automotive systems where small form factors are critical. This specific model represents the standard single-line configuration within that family.

Chip Ferrite Bead Replacement Considerations

Check for direct substitutes within the BLM03 series that match the 80 Ohm impedance and 1 A rating. Ensure any replacement maintains the same 0201 package dimensions and operating temperature range to fit existing footprints without redesign.
