• Manufactured in a QPL certified facility with complete material traceability
• Qualified and tested to AEM Drawing 487070 or DSCC Drawing 03024

Chip Ferrite Bead Applications

• Space electronics
• High reliability military systems
• Harsh environment circuit filtering

Chip Ferrite Bead Procurement Notes

Verify RoHS status as the datasheet indicates non-compliance. Confirm termination type requirements, as tin-lead options are available where pure tin is prohibited. Ensure compatibility with DSCC Drawing 03024 standards if used in qualified space programs. Check specific drawing revisions for manufacturing consistency.

Chip Ferrite Bead Selection Notes

Select this component when high current handling up to 4A is required in a compact 0805 footprint. The low DC resistance minimizes power loss in power lines. Choose based on the specific impedance requirement of 30 Ohms at 100 MHz for EMI suppression. Ensure the operating temperature range meets the environmental conditions of the target application.

Chip Ferrite Bead Part Context

This part belongs to the HRB series of high-reliability ferrite beads manufactured by AEM. These components are distinguished by their qualification for space applications and strict manufacturing controls. The series offers various impedance and current ratings in standard packages like 0603 and 0805.

Chip Ferrite Bead Replacement Considerations

Check for direct equivalents from other manufacturers offering DSCC 03024 qualification. Verify that substitute parts match the 30 Ohm impedance at 100 MHz and support at least 4A DC current. Ensure the replacement maintains the same 0805 package dimensions and thermal characteristics.
