BLM31KN102BH1L

Chip Ferrite Bead Overview

The Murata BLM31KN102BH1L is a single-channel ferrite chip bead in a 1206 (3216 metric) SMD package. It provides 1000 Ohms impedance at 100 MHz with a 25% tolerance. The component supports a maximum DC current of 1.4 A and has a maximum DC resistance of 75 mOhms. It operates between -55°C and +150°C and holds AEC-Q200 qualification.

Chip Ferrite Bead Feature Summary

AEC-Q200 qualified for automotive reliability standards
High impedance performance for power line noise suppression
Compact surface mount design for space-constrained layouts

Chip Ferrite Bead Applications

Automotive power line filtering
DC-DC converter output filtering
Noise suppression on high-current power rails

Chip Ferrite Bead Procurement Notes

Verify the specific suffix BH1L against official Murata documentation to confirm impedance, current rating, and temperature range. Ensure the ordering part number matches the required AEC-Q200 qualification status and package dimensions before finalizing procurement specifications.

Chip Ferrite Bead Selection Notes

Select this component when high current handling up to 1.4 A is required alongside significant noise attenuation. The 1206 footprint offers a balance between current capacity and board space. Verify that the 1000 Ohm impedance at 100 MHz aligns with the target noise frequency spectrum.

Chip Ferrite Bead Part Context

This part belongs to the BLM31KN series of high-current ferrite beads designed for automotive and industrial applications. The series utilizes Murata's proprietary technology to achieve low DC resistance while maintaining high impedance characteristics suitable for power integrity management.

Chip Ferrite Bead Replacement Considerations

Cross-reference with other BLM31KN variants having identical 1206 dimensions and 1.4 A current ratings. Verify impedance values and AEC-Q200 status match requirements before substitution.
