BLM15PX331SN1D

Chip Ferrite Bead Overview

The Murata BLM15PX331SN1D is a single-type chip ferrite bead in the BLM15_Z series, housed in an unshielded 0402 (1005 metric) SMD package. It provides an impedance of 330 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 1.2 A and has a maximum DC resistance of 150 mOhms. It operates within a temperature range of -55°C to +125°C and meets AEC-Q200 qualification standards for automotive applications.

Chip Ferrite Bead Feature Summary

• Provides high-impedance noise suppression for high-current signal lines
• AEC-Q200 qualified for automotive reliability requirements
• Unshielded design suitable for general EMI/RFI attenuation

Chip Ferrite Bead Applications

• Automotive electronic circuit noise filtering
• High-current power line suppression
• General-purpose EMI suppression in compact SMD layouts

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'SN1D' against official Murata documentation to confirm exact packaging and tape-and-reel specifications. Ensure the selected variant matches the required 0402 footprint and 1.2 A current rating for the target application. Cross-reference the AEC-Q200 certification status if automotive compliance is mandatory.

Chip Ferrite Bead Selection Notes

Select this component when a 330 Ohm impedance is required at 100 MHz for circuits carrying up to 1.2 A. The 0402 package offers a compact solution for space-constrained designs. Consider the 150 mOhms DC resistance impact on voltage drop in low-voltage power rails before finalizing the selection.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM15 series of chip ferrite beads, designed for surface-mount technology. The series is characterized by its ability to handle relatively high currents compared to smaller packages, making it suitable for power integrity and noise reduction in dense PCB layouts.

Chip Ferrite Bead Replacement Considerations

The BLM15PX331SZ1D is a documented alternative within the same series offering identical electrical characteristics and package dimensions.
