HRB1206S300J4.00FT

Chip Ferrite Bead Overview

The HRB1206S300J4.00FT is a single-line ferrite bead chip manufactured by AEM, Inc., designed for high-reliability applications. It features a 1206 (3216 metric) surface-mount package with dimensions of 3.20mm x 1.60mm and a maximum height of 1.30mm. The component provides an impedance of 30 Ohms at a test frequency of 100 MHz. It supports a maximum DC current rating of 4A and has a maximum DC resistance (DCR) of 5 milliohms. The device operates within a temperature range of -55°C to +125°C and carries DLA approval.

Chip Ferrite Bead Feature Summary

• DLA-approved high-reliability construction for mission-critical environments
• Low impedance design with minimal DC resistance for efficient signal integrity
• High current handling capability suitable for power line filtering

Chip Ferrite Bead Applications

• Military and aerospace electronic systems
• Defense communication equipment
• Industrial control circuits requiring high reliability

Chip Ferrite Bead Procurement Notes

Verify the specific suffix J4.00FT against official AEM documentation to confirm tolerance and packaging details. Ensure compatibility with existing PCB footprints for the 1206 case size. Confirm that the 4A current rating meets the circuit requirements under expected operating temperatures. Check for any specific handling instructions related to its high-reliability classification.

Chip Ferrite Bead Selection Notes

Select this component when DLA-approved ferrite beads are required for noise suppression in high-current paths. The low DCR minimizes voltage drop across the filter. The 1206 package offers a balance between current capacity and board space. Verify that the 30 Ohm impedance at 100 MHz aligns with the target noise frequencies in the application design.

Chip Ferrite Bead Part Context

This part belongs to the HRB series of high-reliability ferrite chips from AEM, Inc. These components are specifically engineered for defense and aerospace sectors where standard commercial parts may not suffice. The series includes various impedances and current ratings within standardized packages like 0603 and 1206.

Chip Ferrite Bead Replacement Considerations

Direct substitutes must be DLA-approved ferrite beads in the 1206 package with similar electrical characteristics. Verify impedance curves and saturation currents carefully. Generic commercial ferrites are not suitable replacements due to reliability standards.
