28F0181-1SR-10

Overview

The Laird-Signal Integrity Products 28F0181-1SR-10 is a surface-mount ferrite bead designed for power and signal line noise suppression. It features a 3318 (8546 Metric) package with J-leads, offering an impedance of 115 Ohms at 100 MHz. The component supports a maximum rated current of 10A and maintains a low DC resistance of 1mOhm. It operates within a temperature range of -40°C to 125°C.

Feature Summary

• Provides broadband frequency noise suppression for electronic circuits
• Designed for integration into power and general signal lines
• Utilizes J-lead surface mount packaging for automated assembly

Applications

• Power line filtering in high-current applications
• General signal line noise reduction
• High-speed digital circuit EMI mitigation

Procurement Notes

Verify the specific suffix '10' against official datasheets to confirm termination plating specifications, as variations may exist. Confirm RoHS compliance status directly with the manufacturer or authorized distributors, as historical data indicates potential non-compliance for certain variants in this series. Ensure the 3318 footprint matches your PCB design requirements before ordering.

Selection Notes

Select this component when a 10A current rating and 115 Ohm impedance at 100 MHz are required for surface-mount designs. The 3318 package size offers a compact solution for space-constrained boards. Compare against other 28-series beads if different impedance values or lead styles are needed for specific filtering characteristics.

Part Context

This part belongs to the Laird 28 series of ferrite beads, which are widely used for electromagnetic interference (EMI) suppression. The series includes various packages and impedance ratings tailored for different current loads and frequency responses, serving as critical passive components in modern electronic systems.

Replacement Considerations

Direct substitutes include other Laird 28-series ferrite beads with similar 10A ratings and 3318 footprints. Verify impedance curves and physical dimensions carefully when cross-referencing with generic equivalents from other manufacturers.
