BLM15PX330SH1D

Chip Ferrite Bead Overview

The Murata BLM15PX330SH1D is a single ferrite bead in a 0402 (1005 metric) surface-mount package. It provides an impedance of 33 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 5 A and has a maximum DC resistance of 22 mOhms. It operates within a temperature range of -55°C to +125°C and meets the AEC-Q200 automotive qualification standard.

Chip Ferrite Bead Feature Summary

• Provides high-current suppression capability for power lines
• Automotive-grade reliability certified under AEC-Q200 standards
• Compact 0402 footprint suitable for dense PCB layouts

Chip Ferrite Bead Applications

• DC power line filtering in automotive infotainment systems
• Noise suppression on high-current automotive data buses
• EMI reduction in vehicle electronic control units

Chip Ferrite Bead Procurement Notes

Verify the specific suffix SH1D against official Murata documentation to confirm the 5A current rating and 33 Ohm impedance specifications. Ensure the ordering part number matches the required automotive grade and package dimensions. Cross-reference datasheet parameters with design requirements before procurement.

Chip Ferrite Bead Selection Notes

Select this component when high current handling is required in a small 0402 package. The 5A rating distinguishes it from lower-current variants in the BLM15 series. Verify that the 33 Ohm impedance at 100 MHz aligns with target noise frequencies. Confirm AEC-Q200 compliance is necessary for the application environment.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM15 series of chip ferrite beads, designed for EMI suppression. The PX designation typically indicates high-current capabilities within the series. It shares the standard 0402 mechanical outline with other BLM15 variants but differs in magnetic material properties to support higher saturation currents.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include BLM15PX330SZ1D and BLM15PX330SN1D. Verify that alternative suffixes maintain the same 5A current rating and 33 Ohm impedance. Check if replacement parts share the AEC-Q200 qualification status.
