HRB0603S181M.400FT

Chip Ferrite Bead Overview

The HRB0603S181M.400FT is a high-reliability ferrite chip bead manufactured by AEM, Inc., designed for space and mission-critical applications. It features a 0603 (1608 metric) surface-mount package with an impedance of 180 ohms at 100 MHz and a tolerance of ±20%. The component supports a maximum DC current of 400 mA and has a maximum DC resistance of 250 milliohms. It operates within a temperature range of -55°C to +125°C. Qualified to DSCC Drawing 03024, it utilizes tin-lead terminations to prevent tin whiskering.

Chip Ferrite Bead Feature Summary

• Manufactured in a QPL certified facility with complete material and process traceability for high reliability environments.
• Qualified and tested to AEM Drawing 487070 or DSCC Drawing 03024 standards for space applications.
• Utilizes tin-lead terminations to ensure compliance where pure tin termination is prohibited due to whisker risks.

Chip Ferrite Bead Applications

• Space electronics requiring DSCC qualified components
• Aerospace systems demanding high reliability filtering
• Defense applications with strict environmental constraints

Chip Ferrite Bead Procurement Notes

Verify the specific ordering suffix and termination type against project requirements, as this series uses tin-lead finishes suitable for environments prohibiting pure tin. Confirm that the 0603 footprint and electrical parameters align with the design specifications. Ensure compatibility with the intended manufacturing processes for high-reliability assemblies.

Chip Ferrite Bead Selection Notes

Select this component when a DSCC qualified ferrite bead is required for critical systems. The 0603 size offers a compact solution for EMI suppression. Consider the 400 mA current rating and 180 ohm impedance at 100 MHz for circuit compatibility. The tin-lead termination is essential if tin whisker mitigation is a design constraint.

Chip Ferrite Bead Part Context

This part belongs to the HRB Series, which are high-reliability ferrite chip beads designed for space and other high-reliability uses. The series is notable for being the first and only DSCC approved ferrite chip bead of its kind, manufactured with space-qualified materials and terminations to ensure performance in extreme conditions.

Chip Ferrite Bead Replacement Considerations

Direct substitutes must be DSCC Drawing 03024 qualified. Verify impedance, current rating, and termination composition. Generic commercial ferrite beads do not meet the traceability and qualification standards of this component.
