BLM15PX471BH1D

Chip Ferrite Bead Overview

The Murata BLM15PX471BH1D is a shielded ferrite chip bead in a 0402 (1005 metric) surface-mount package. It provides an impedance of 470 Ohms at 100 MHz with a 25% tolerance and a maximum DC resistance of 200 mOhms. Rated for a continuous DC current of 1 A, it operates within a temperature range of -55°C to +125°C. The component meets AEC-Q200 automotive qualification standards and utilizes conductive glue termination.

Chip Ferrite Bead Feature Summary

• AEC-Q200 qualified for automotive reliability
• Shielded construction to minimize electromagnetic interference
• High current handling capability of 1 A
• Compact 0402 footprint for dense PCB layouts

Chip Ferrite Bead Applications

• DC power line filtering in automotive electronics
• EMI suppression on high-speed signal lines
• Noise reduction in compact mobile devices

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'BH1D' against official Murata documentation to confirm the exact operating temperature range and packaging details, as variations exist within the BLM15PX series. Ensure compatibility with automated pick-and-place equipment due to the small 0402 form factor and conductive glue termination style.

Chip Ferrite Bead Selection Notes

Select this component when shielding is required to prevent magnetic field leakage in close-proximity circuits. The 1 A rating supports moderate power applications, while the 470 Ohm impedance targets noise frequencies around 100 MHz. Verify that the 200 mOhms DC resistance aligns with system voltage drop requirements.

Chip Ferrite Bead Part Context

This part belongs to the BLM15PX series, designed specifically for automotive and industrial applications requiring robust EMI suppression. The PX designation indicates a shielded type, distinguishing it from unshielded variants like the BLB or BLD series which may have different thermal or magnetic characteristics.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include other shielded 0402 ferrite beads with similar 470 Ohm impedance and 1 A ratings, such as the BLM15PX471SH1D, provided the temperature range and termination specifications match the design requirements.
