BLM21PG220SN1D

Chip Ferrite Bead Overview

The Murata BLM21PG220SN1D is a single-line ferrite bead chip designed for power line noise suppression. It operates in the 0805 (2012 metric) surface-mount package with dimensions of 2.00mm x 1.25mm and a maximum height of 1.05mm. The component provides an impedance of 22 Ohms at 100 MHz and supports a rated current of 6A. Its maximum DC resistance is 9 milliohms. It functions within a temperature range of -55°C to +125°C and complies with RoHS3 standards.

Chip Ferrite Bead Feature Summary

• Provides effective electromagnetic interference suppression on power lines through high-current handling capabilities.
• Utilizes a compact 0805 footprint suitable for dense surface-mount assembly requirements.
• Maintains low DC resistance to minimize voltage drop and power loss during operation.

Chip Ferrite Bead Applications

• Power supply circuit filtering
• EMI suppression filters
• Automotive electronic systems

Chip Ferrite Bead Procurement Notes

Verify the complete part number including suffixes to ensure correct impedance, current rating, and packaging configuration. Confirm RoHS3 compliance status and moisture sensitivity level requirements against specific project constraints before finalizing procurement orders.

Chip Ferrite Bead Selection Notes

Select this component when high current capacity up to 6A is required in a standard 0805 package. Ensure the target application frequency aligns with the 22 Ohm impedance specification at 100 MHz. Verify that the thermal operating range meets environmental demands.

Chip Ferrite Bead Part Context

This component belongs to the EMIFIL BLM21 series, which focuses on high-current noise suppression applications. It shares the physical 0805 dimensions with other variants but differs in electrical characteristics such as impedance and current ratings based on the specific suffix codes.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include BLM21PG220SH1D, which shares identical electrical specifications and package type. Verify equivalent current ratings and impedance values when considering alternative manufacturers or series.
