BLM03HG122SH1D

Chip Ferrite Bead Overview

The Murata BLM03HG122SH1D is a surface-mount ferrite bead in the 0201 (0603 metric) package. It provides an impedance of 1200 ohms at 100 MHz with a rated current of 100 mA and a DC resistance of 3.5 ohms. The component operates within a temperature range of -55°C to +125°C and has a maximum height of 0.3 mm.

Chip Ferrite Bead Feature Summary

• Designed for noise suppression in small electronic equipment
• Suitable for high-frequency signal line filtering applications

Chip Ferrite Bead Applications

• Noise suppression in compact consumer electronics
• Signal line filtering in portable devices
• High-frequency interference reduction in automotive infotainment systems

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'H' against official Murata documentation to confirm it denotes the correct impedance tolerance or material variant, as suffixes define precise electrical characteristics. Ensure the ordering part number matches the required 100 mA rating and 1200 Ohm impedance specifications exactly.

Chip Ferrite Bead Selection Notes

Select this component when space constraints require a 0201 footprint for high-impedance noise filtering. It is appropriate for circuits requiring 100 mA current handling where significant attenuation at 100 MHz is necessary. Consider the low DC resistance for minimal signal loss in power-sensitive lines.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the BLM03 series from Murata Electronics, which offers various impedance values and current ratings in the 0201 package. The series is engineered for surface-mount assembly, providing reliable noise suppression solutions for modern miniaturized electronic designs across multiple industries.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include other Murata BLM03 series parts with matching 1200 Ohm impedance and 100 mA ratings, such as BLM03HG122SN1D if the suffix variation is verified compatible.
