BLM15BA220SZ1D

Chip Ferrite Bead Overview

The Murata BLM15BA220SZ1D is a chip ferrite bead in the BLM15_Z series, housed in a 0402 (1005 metric) SMD package. It provides an impedance of 22 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 300 mA and has a maximum DC resistance of 200 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

• Designed to function as a resistor at noise frequencies to reduce resonance possibilities
• AEC-Q200 qualified for automotive reliability requirements
• Unshielded surface-mount construction

Chip Ferrite Bead Applications

• Automotive electronic circuits requiring EMI suppression
• High-frequency noise filtering in compact PCB layouts
• Power line decoupling in mobile devices

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'SZ1D' against official Murata documentation to confirm packaging and tape-and-reel specifications. Ensure the selected variant matches the required impedance tolerance and current rating for the target circuit design before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when a low-profile 0402 footprint is required for high-current noise suppression. The 300 mA rating distinguishes it from lower-current variants in the same series. Verify that the 22 Ohm impedance at 100 MHz aligns with the specific noise spectrum of the application.

Chip Ferrite Bead Part Context

This part belongs to the BLM15_Z series of chip ferrite beads manufactured by Murata Electronics. These components are engineered to suppress electromagnetic interference in digital circuits. The series offers various impedance values within a standardized 0402 package size to facilitate consistent board layout practices across different product lines.

Chip Ferrite Bead Replacement Considerations

BLM15BB220SZ1D and BLM15BA220SZ1D share identical electrical parameters including 22 Ohms impedance and 300 mA current rating. Verify package compatibility and suffix differences before substitution.
