BLM15HB221SN1D

Chip Ferrite Bead Overview

The Murata BLM15HB221SN1D is a single-line chip ferrite bead in the BLM15_SN series, housed in a 0402 (1.0mm x 0.5mm) surface-mount package. It provides an impedance of 220Ω at 100MHz with a maximum DC resistance of 1Ω and a rated current of 250mA. The component operates within a temperature range of -55°C to +125°C and complies with RoHS and REACH standards.

Chip Ferrite Bead Feature Summary

• Monolithic ferrite construction for effective high-frequency noise suppression
• Compact 0402 footprint suitable for space-constrained PCB layouts
• Single-channel design for targeted signal line filtering

Chip Ferrite Bead Applications

• EMI suppression filters
• High-speed signal lines
• General-purpose noise reduction

Chip Ferrite Bead Procurement Notes

Verify the specific suffix 'D' indicates tape-and-reel packaging as per Murata's numbering convention. Confirm that the 250mA current rating aligns with thermal constraints in the target application. Ensure compliance with RoHS and REACH directives is required for the project.

Chip Ferrite Bead Selection Notes

Select this component when a 220Ω impedance at 100MHz is required in a 0402 package. Consider the 250mA current limit against peak load requirements. Compare with BLM15BB or BLM15AG series variants if higher current handling or lower DC resistance is necessary for the circuit design.

Chip Ferrite Bead Part Context

This part belongs to the BLM15_SN series of chip ferrite beads from Murata. The series offers various impedance values and current ratings within the standard 0402 package size, providing designers with options for different noise suppression profiles while maintaining a consistent form factor for manufacturing.

Chip Ferrite Bead Replacement Considerations

BLM15HB221SN1B and BLM15HB221SN1J are documented substitutes within the same series.
