BLM15HB221SZ1D

Chip Ferrite Bead Overview

The Murata BLM15HB221SZ1D is a chip ferrite bead designed for high-frequency noise suppression in surface-mount applications. It features an unshielded construction within a compact 0402 (1005 metric) package, measuring 1.0 mm in length, 0.5 mm in width, and 0.5 mm in height. The component provides an impedance of 220 Ohms at a test frequency of 100 MHz with a tolerance of 25%. It supports a maximum DC current of 250 mA and exhibits a maximum DC resistance of 1 Ohm. The device operates reliably within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification for automotive standards.

Chip Ferrite Bead Feature Summary

• Provides effective electromagnetic interference filtering for single signal lines through high-impedance characteristics at target frequencies.
• Features an unshielded design suitable for general-purpose noise suppression without magnetic coupling concerns.
• Complies with AEC-Q200 qualification standards, ensuring reliability for demanding automotive electronic environments.

Chip Ferrite Bead Applications

• High-speed signal line noise filtering
• Automotive electronic circuit protection
• EMI suppression filters

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'SZ1D' against official Murata documentation to confirm exact packaging and tape specifications. Ensure that the selected variant matches the required impedance tolerance and current rating for the target application. Cross-reference the AEC-Q200 status if automotive compliance is mandatory. Confirm RoHS3 compliance requirements prior to ordering to meet environmental regulations.

Chip Ferrite Bead Selection Notes

Select this component when a 220 Ohm impedance at 100 MHz is required for a single-line signal path. The 250 mA current rating dictates suitability for low-power signal circuits rather than power rails. The 0402 footprint constrains layout density but offers standard compatibility. Consider the 1 Ohm DC resistance impact on signal integrity for sensitive analog lines.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM15 series of chip ferrite beads, specifically tailored for compact electronics. The BLM15HB designation indicates a specific impedance and current characteristic within the broader family. It serves as a passive component essential for maintaining signal purity in modern digital and mixed-signal systems.

Chip Ferrite Bead Replacement Considerations

Consult official Murata substitution guides for equivalent parts within the BLM15 series. Verify that alternative components match the 220 Ohm impedance, 250 mA rating, and 0402 package dimensions exactly.
