BLM15AX221SN1D

Chip Ferrite Bead Overview

The Murata BLM15AX221SN1D is a surface-mount chip ferrite bead in the 0402 (1005 metric) package. It provides an impedance of 220 Ω at 100 MHz with a maximum DC resistance of 80 mΩ and a rated current of 600 mA. The component operates within a temperature range of -55°C to +125°C, features a height of 0.5 mm, and complies with RoHS standards.

Chip Ferrite Bead Feature Summary

• Monolithic ferrite construction for high-frequency noise suppression
• Compact 0402 surface-mount footprint for space-constrained designs
• High current handling capability suitable for power line filtering

Chip Ferrite Bead Applications

• EMI suppression filters
• General-purpose noise reduction circuits
• Power supply line filtering

Chip Ferrite Bead Procurement Notes

Verify that the specific suffix 'AX' matches the required performance characteristics, as it denotes a distinct variant within the BLM15 family. Confirm compliance with project-specific environmental directives such as RoHS and REACH. Ensure the selected packaging format aligns with automated assembly requirements. Cross-reference the manufacturer's latest datasheet to validate electrical parameters against design specifications before finalizing procurement.

Chip Ferrite Bead Selection Notes

Select this component when a 0402 footprint is required alongside a 220 Ω impedance at 100 MHz. The 600 mA rated current distinguishes it from lower-current variants like the BB series. Consider the low DC resistance of 80 mΩ to minimize voltage drop in power applications. Verify thermal stability requirements against the specified operating temperature range.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM15_SN series of chip ferrite beads. The series offers various impedance and current ratings within the standard 0402 package size. Different suffixes indicate variations in material properties and current handling capabilities, allowing designers to select components optimized for specific signal integrity or power filtering needs.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include other BLM15 series parts with identical 220 Ω impedance and 0402 dimensions but different current ratings, such as BLM15AG221SN1D (450 mA) or BLM15BB221SN1D (200 mA). Verify that the alternative part's current rating meets the application's peak load requirements.
