HRB0805S101K1.00FT

Chip Ferrite Bead Overview

The AEM HRB0805S101K1.00FT is a high-reliability ferrite chip bead in an 0805 (2012 metric) surface-mount package. It provides 100 Ohms impedance at 100 MHz with a tolerance of +/-10%. The component supports a maximum DC current of 1A and has a maximum DC resistance of 200 mOhms. It operates within a temperature range of -55°C to +125°C. Dimensions are 2.00mm x 1.25mm x 1.10mm.

Chip Ferrite Bead Feature Summary

• Qualified for space and high-reliability applications under DSCC Drawing 03024
• Features nickel barrier terminations with solder plate finish
• Manufactured with space-qualified materials and full process traceability

Chip Ferrite Bead Applications

• Space electronics filtering
• High reliability military circuits
• Harsh environment signal integrity management

Chip Ferrite Bead Procurement Notes

Verify the specific termination finish required, as the K suffix denotes nickel barrier/solder plate, distinct from tin-lead options. Confirm RoHS status, as this high-reliability series may not be compliant. Ensure the 100 Ohm impedance at 100 MHz matches the target noise suppression frequency. Validate that the 1A current rating suits the circuit load.

Chip Ferrite Bead Selection Notes

Select this part when MIL-spec or space-grade reliability is mandatory. The 0805 footprint offers a balance between current handling and board space. Compare against standard commercial ferrites if cost is primary; however, choose HRB for radiation hardness and material traceability requirements. Ensure the 200 mOhms DCR does not cause excessive voltage drop in power lines.

Chip Ferrite Bead Part Context

This component belongs to the AEM HRB Series, designed specifically for high-reliability environments. Unlike standard commercial beads, these are manufactured in QPL-certified facilities. The series covers various EIA sizes, providing engineers with standardized, qualified components for aerospace and defense projects requiring strict quality control.

Chip Ferrite Bead Replacement Considerations

Direct substitutes include other DSCC 03024 qualified parts from manufacturers like Johanson Technology or TDK, provided they match the 0805 size, 100 Ohm impedance, and 1A rating. Verify termination compatibility, as lead-free alternatives may differ physically.
