BLM18PG221SZ1D

Chip Ferrite Bead Overview

The Murata BLM18PG221SZ1D is a single-line chip ferrite bead in the BLM18P series, housed in a 0603 (1608 metric) surface-mount package measuring 1.6 mm x 0.8 mm x 0.8 mm. It provides an impedance of 220 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 1.4 A and features a maximum DC resistance of 100 mOhms. It operates within a temperature range of -55°C to +125°C and complies with RoHS standards.

Chip Ferrite Bead Feature Summary

• Provides high impedance for effective electromagnetic interference suppression
• Supports high continuous current handling capability
• Designed for compact surface-mount integration

Chip Ferrite Bead Applications

• Power supply line filtering
• EMI suppression filters
• Signal line noise reduction

Chip Ferrite Bead Procurement Notes

Verify the suffix 'SZ1D' against official Murata documentation to confirm specific packaging or material variations. Ensure compatibility with standard 0603 footprints during PCB layout. Cross-reference the impedance value at 100 MHz with circuit requirements. Confirm RoHS compliance status through the manufacturer's latest datasheet before final procurement approval.

Chip Ferrite Bead Selection Notes

Select this component when a 0603 footprint is required with a 1.4 A current rating. The 220 Ohm impedance at 100 MHz suits general-purpose noise suppression. Consider the 100 mOhm DC resistance for minimal voltage drop. Evaluate thermal performance within the -55°C to +125°C operating range for the target application environment.

Chip Ferrite Bead Part Context

This part belongs to the Murata BLM18P series of chip ferrite beads. It shares the 0603 form factor with other variants but differs in impedance and current ratings. The series is designed for surface-mount technology applications requiring reliable EMI filtering in space-constrained electronic assemblies.

Chip Ferrite Bead Replacement Considerations

BLM18PG221SN1D offers identical electrical specifications including 220 Ohm impedance, 1.4 A current rating, and 0603 dimensions. Verify that the suffix change does not alter packaging or material properties as per official substitution guidelines.
